Ivy-DE RNA Motif
The ivy-DE RNA motif is a conserved RNA structure that was Bioinformatics discovery of non-coding RNAs, discovered by bioinformatics. ivy-DE motifs are found in the genus ''Pseudomonas''. ivy-DE motif RNAs likely function as cis-regulatory elements, in view of their positions that are consistently downstream of protein-coding genes. However, the RNA is most likely located in the three prime untranslated region, 3′ UTR of the regulated (upstream) genes, even though ''cis''-regulatory RNAs in bacteria generally reside in the five prime untranslated region, 5′ UTR. No genetic elements are consistently located downstream of ivy-DE motif RNAs, so the RNAs could be regulators within the 3′ UTR. However, it is possible that they are co-transcribed with the upstream genes and function rather as small RNAs. ivy-DE motif RNAs are downstream of ivy (inhibitor of vertebrate lysozyme) genes. ivy proteins are used by bacteria and have shown to be potent inhibitors of vertebrate lysoz ...

Secondary Structure
Protein secondary structure is the local spatial conformation of the polypeptide backbone excluding the side chains. The two most common Protein structure#Secondary structure, secondary structural elements are alpha helix, alpha helices and beta sheets, though beta turns and omega loops occur as well. Secondary structure elements typically spontaneously form as an intermediate before the protein protein folding, folds into its three dimensional protein tertiary structure, tertiary structure. Secondary structure is formally defined by the pattern of hydrogen bonds between the Amine, amino hydrogen and carboxyl oxygen atoms in the peptide backbone chain, backbone. Secondary structure may alternatively be defined based on the regular pattern of backbone Dihedral angle#Dihedral angles of proteins, dihedral angles in a particular region of the Ramachandran plot regardless of whether it has the correct hydrogen bonds. The concept of secondary structure was first introduced by Kaj Ulrik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
