हिस्टीडिन इसके अंग्रेजी अर्थ का उदाहरण

Analysis of the aromatic amino acids phenylalanine, tyrosine, histidine, and tryptophan indicates that dimers of these side chains have many possible stabilizing interactions at distances larger than the average van der Waals radii.

This observation appears contradictory to standard chemical reactivity, however the presence of a favourable interaction between the positive imidazolium ion of the catalytic histidine and the negatively charged carboxyl-group of the iodoacetate is the reason for the increased relative activity of iodoacetamide.

Four distinct classes of phytase have been characterized in the literature: histidine acid phosphatases (HAPS), beta-propeller phytases (BPPs), purple acid phosphatases (PAPs), and most recently, protein tyrosine phosphatase-like phytases (PTP-like phytases).

Most of the known phytases belong to a class of enzyme called histidine acid phosphatases (HAPs).

Without the histidine (H) residue ATP7A may not function properly.
