Chalice
A chalice (from Latin 'cup', taken from the Ancient Greek () 'cup') is a drinking cup raised on a stem with a foot or base. Although it is a technical archaeological term, in modern parlance the word is now used almost exclusively for the cups used in Christian liturgy as part of a service of the Eucharist, such as a Catholic mass. These are normally made of metal, but neither the shape nor the material is a requirement. Most have no handles, and in recent centuries the cup at the top has usually been a simple flared shape. Historically, the same shape was used for elite secular vessels, and many individual examples have served both secular and liturgical uses over their history, for example the Lacock Cup and Royal Gold Cup, both late medieval cups. Cups owned by churches were much more likely to survive, as secular drinkware in precious metal was usually melted down when it fell out of fashion. The same general cup shape is also called a goblet (from Old French , di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kelch Motif
The Kelch motif is a region of protein sequence found widely in proteins from bacteria and eukaryotes. This sequence motif is composed of about 50 amino acid residues which form a structure of a four stranded beta-sheet "blade". This sequence motif is found in between five and eight tandem copies per protein which fold together to form a larger circular solenoid structure called a beta-propeller domain. Proteins containing Kelch motifs The Kelch motif is widely found in eukaryotic and bacterial species. Notably the human genome contains around 100 proteins containing the Kelch motif. Within individual proteins the motif occurs multiple times. For example, the motif appears 6 times in ''Drosophila'' egg-chamber regulatory protein. The motif is also found in mouse protein MIPP and in a number of poxviruses. In addition, kelch repeats have been recognised in alpha- and beta-scruin, in galactose oxidase from the fungus '' Dactylium dendroides'', and in the ''Escherichia col ...

Kelch Protein
Kelch proteins (and Kelch-like proteins) are a widespread group of proteins that contain multiple Kelch motifs. The kelch domain generally occurs as a set of five to seven kelch tandem repeats that form a β-propeller tertiary structure. Kelch-repeat β-propellers are generally involved in protein–protein interactions, though the large diversity of domain architectures and limited sequence identity between kelch motifs make characterisation of the kelch superfamily difficult. Structure The N-terminus of several Kelch proteins contain other protein domains, including Discoidin, F-box, and Broad-complex, Tramtrack, Bric-a-Brac/Poxvirus Zinc finger (BTB/POZ) domains. Kelch proteins may also only have a β-propeller architecture. The BTB domain of kelch proteins (if present) allows the formation of homo- or heterodimers that mediate protein–protein interactions. The C-terminus of Kelch proteins contains kelch repeats. Each kelch repeat is a sequence of 44–55 amino acid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trappist Ale
Trappist beer is brewed by Trappist monks. Thirteen Trappist monasteries—six in Belgium, two in the Netherlands, and one each in Austria, Italy, England, France, and Spain— produce beer, but the ''Authentic Trappist Product'' label is assigned by the International Trappist Association (ITA) to just ten breweries that meet their strict criteria. , Achel is no longer recognized as a Trappist brewery because it does not have any monks. History The Catholic Trappist order originated in the Cistercian monastery of La Trappe, France. Various Cistercian congregations existed for many years, and by 1664 the abbot of La Trappe felt that the Cistercians were becoming too liberal. He introduced strict new rules in the abbey and the Strict Observance was born. Since this time, many of the rules have been relaxed. However, a fundamental tenet that monasteries should be self-supporting is still maintained by these groups. Monastery brewhouses, from different religious orders, have existed ...
