Th1L04: Amino Acids and Proteins/ Protein Structure and Function (FCs)
Cards in this deck (8)
- 1Define glycosylationthe reaction in which a carbohydrate, i.e. a glycosyl donor, is attached to a hydroxyl or other functional group of another molecule (a glycosyl acceptor)
- 2Phosphorylation (2 roles)• Cell signal transduction, e.g. phosphorylation of tyr in insulin receptors
• Change in activity of enzyme, e.g. phosphorylation of glycogen phosphorylase in response to glucagon - 3Methylation is vital for what processGene expression (specifically histones)
- 4Primary structureSequence of aa in peptide chain
- 5Secondary structureFolding/coiling of peptide chain (usually into an alpha-helix to a beta-pleated sheet
- 6Tertiary structure3D structure, complete with various folds
- 7Quaternary structure· Folded peptide chains join together
· May consist of a number of subunits - 8Supersecondary structure· Combinations of alpha-helix and beta-sheet form common domains found in protein
· 100s exist
· Quite common
· Certain arrangements frequently found because they are the most energetically stable
