Serine Dehydratase
Serine dehydratase or L-serine ammonia lyase (SDH) is in the β-family of pyridoxal phosphate-dependent (PLP) enzymes. SDH is found widely in nature, but its structural and properties vary among species. SDH is found in yeast, bacteria, and the cytoplasm of mammalian hepatocytes. SDH catalyzes is the deamination of L-serine to yield pyruvate, with the release of ammonia. This enzyme has one substrate, L-serine, and two products, pyruvate and NH3, and uses one cofactor, pyridoxal phosphate (PLP). The enzyme's main role is in gluconeogenesis in the liver's cytoplasm. Nomenclature Serine Dehydratase is also known as: * L-serine ammonia-lyase * Serine deaminase * L-hydroxyaminoacid dehydratase * L-serine deaminase * L-serine dehydratase * L-serine hydro-lyase Structure The holoenzyme SDH contains 319 residues, one PLP cofactor molecule. The overall fold of the monomer is very similar to that of other PLP-dependent enzymes of the Beta-family. The enzyme contains a large c ...

SDHD
Succinate dehydrogenase biquinonecytochrome b small subunit, mitochondrial (CybS), also known as succinate dehydrogenase complex subunit D (SDHD), is a protein that in humans is encoded by the ''SDHD'' gene. Names previously used for SDHD were PGL and PGL1. Succinate dehydrogenase is an important enzyme in both the citric acid cycle and the electron transport chain. Structure The SDHD gene is located on chromosome 11 at locus 11q23 and it spans 8,978 base pairs. There are pseudogenes for this gene on chromosomes 1, 2, 3, 7, and 18. The SDHD gene produces a 17 kDa protein composed of 159 amino acids. The SDHD protein is one of the two integral transmembrane subunits anchoring the four-subunit succinate dehydrogenase (Complex II) protein complex to the matrix side of the mitochondrial inner membrane. The other transmembrane subunit is SDHC. The SDHC/SDHD dimer is connected to the SDHB electron transport subunit which, in turn, is connected to the SDHA subunit. ...

Society For Digital Humanities
The Canadian Society for Digital Humanities is a Canadian scholarly association. Its full name is Society for Digital Humanities/''Société canadienne des humanités numériques'' (CSDH-SCHN). The CSDH-SCHN was founded as the COCH/COSH or Consortium for Computers in the Humanities/ ''Consortium pour ordinateurs en sciences humaines'' in 1986. The organization changed its name to the Society for Digital Humanities/Société pour l'étude des médias interactifs (SDH/SEMI), but became CSDH-SCHN after 2007, when it was enfranchised by the Alliance of Digital Humanities Organizations. The CSDH-SCHN meets every year as part of the Congress of the Social Sciences and Humanities organized by the Canadian Federation for the Humanities and Social Sciences. Our objective is to draw together humanists who are engaged in digital and computer-assisted research, teaching, and creation. The society fosters work in the digital humanities in Canada's two official languages, and champions interact ...

Social Democrats Of Croatia
The Social Democratic Party of Croatia ( hr, Socijaldemokratska partija Hrvatske, SDP) is a social-democratic political party in Croatia. The SDP is anti-fascist, progressive, and strongly pro-European. The SDP was formed in 1990 as the successor of the League of Communists of Croatia, Croatian branch of the League of Communists of Yugoslavia, which had governed Croatia within the Yugoslav federation since World War II. The party first won the elections in 2000 and formed a coalition government headed by Ivica Račan. After losing the 2003 general election, the party remained in opposition for eight years. In the 2011 parliamentary election, SDP won 61 out of 151 seats in the Croatian Parliament, and managed to form the 12th Croatian Government under Zoran Milanović with its partners from the Kukuriku coalition. After SDP and its coalition partners failed to achieve an agreement on forming a new government following the 2015 general election, the party returned to the opposi ...

St David's Hall
St David's Hall (Welsh: ''Neuadd Dewi Sant'') is a performing arts and conference venue in the heart of Cardiff, Wales. St David's Hall is the National Concert Hall and Conference Centre of Wales. It hosts the annual Welsh Proms and the biennial BBC Cardiff Singer of the World competition.

Synchronous Digital Hierarchy
Synchronous optical networking (SONET) and synchronous digital hierarchy (SDH) are standardized protocols that transfer multiple digital bit streams synchronously over optical fiber using lasers or highly coherent light from light-emitting diodes (LEDs). At low transmission rates data can also be transferred via an electrical interface. The method was developed to replace the plesiochronous digital hierarchy (PDH) system for transporting large amounts of telephone calls and data traffic over the same fiber without the problems of synchronization. SONET and SDH, which are essentially the same, were originally designed to transport circuit mode communications (e.g., DS1, DS3) from a variety of different sources, but they were primarily designed to support real-time, uncompressed, circuit-switched voice encoded in PCM format. The primary difficulty in doing this prior to SONET/SDH was that the synchronization sources of these various circuits were different. This meant that e ...

SDHC
Secure Digital, officially abbreviated as SD, is a proprietary non-volatile flash memory card format developed by the SD Association (SDA) for use in portable devices. The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita) and Toshiba as an improvement over MultiMediaCards (MMCs), and has become the industry standard. The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products. The companies also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards. SDA today has about 1,000 member companies. The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility. History 1999–2003: Creation In 1999, SanDisk, Panasonic (Matsushita), and Toshiba agreed to develop and ma ...

SDHB
Succinate dehydrogenase biquinoneiron-sulfur subunit, mitochondrial (SDHB) also known as iron-sulfur subunit of complex II (Ip) is a protein that in humans is encoded by the ''SDHB'' gene. The succinate dehydrogenase (also called SDH or Complex II) protein complex catalyzes the oxidation of succinate (succinate + ubiquinone => fumarate + ubiquinol). SDHB is one of four protein subunits forming succinate dehydrogenase, the other three being SDHA, SDHC and SDHD. The SDHB subunit is connected to the SDHA subunit on the hydrophilic, catalytic end of the SDH complex. It is also connected to the SDHC/SDHD subunits on the hydrophobic end of the complex anchored in the mitochondrial membrane. The subunit is an iron-sulfur protein with three iron-sulfur clusters. It weighs 30 kDa. Structure The gene that codes for the SDHB protein is nuclear, not mitochondrial DNA. However, the expressed protein is located in the inner membrane of the mitochondria. The location of the gene in hum ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

SDHA
Succinate dehydrogenase complex, subunit A, flavoprotein variant is a protein that in humans is encoded by the ''SDHA'' gene. This gene encodes a major catalytic subunit of succinate-ubiquinone oxidoreductase, a complex of the mitochondrial respiratory chain. The complex is composed of four nuclear-encoded subunits and is localized in the mitochondrial inner membrane. SDHA contains the FAD binding site where succinate is deprotonated and converted to fumarate. Mutations in this gene have been associated with a form of mitochondrial respiratory chain deficiency known as Leigh Syndrome. A pseudogene has been identified on chromosome 3q29. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. Structure The ''SDHA'' gene is located on the p arm of chromosome 5 at locus 15 and is composed of 16 exons. The SDHA protein encoded by this gene is 664 amino acids long and weighs 72.7 kDA. SDHA protein has four subdomains, including capp ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
