Webb7 jan. 2024 · The alpha-helix structure is formed when the CO group of each amino acid is hydrogen-bonded to the NH group of the amino acid that is present four residues ahead in the linear sequence. The α-helical structure depends on the intramolecular hydrogen bonding between the NH and CO groups of peptide bonds. b. Beta-pleated structure Histidine is synthesized from phosphoribosyl pyrophosphate (PRPP), which is made from ribose-5-phosphate by ribose-phosphate diphosphokinase in the pentose phosphate pathway. The first reaction of histidine biosynthesis is the condensation of PRPP and adenosine triphosphate (ATP) by the enzyme ATP … Visa mer Histidine (symbol His or H) is an essential amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated –NH3 form under biological conditions), a carboxylic acid group … Visa mer The conjugate acid (protonated form) of the imidazole side chain in histidine has a pKa of approximately 6.0. Thus, below a pH of 6, the imidazole ring is mostly protonated (as described by the Henderson–Hasselbalch equation).

The mature form is a 275-residue globular protein with several alpha-helices, and a large beta-sheet. The N-terminal contains an I9 propeptide domain (InterPro: IPR010259) that assists the folding of subtilisin. Proteolytic removal of the domain activates the enzyme.
