Subunits

Subunits Comment Organism
homodimer secondary structure analysis, at the N-terminal end of the polypeptide chain, the hood domain is located encompassing a beta-sheet made of two antiparallel beta-strands, beta1 and beta2, and a disordered fragment following the beta2 strand, extending to the alpha1 helix Thermus thermophilus
More enzyme crystals belonging to the P21 spatial group contain six identical enzyme subunits per asymmetric unit. Subunits are connected with a double axis pairwise and form three dimers (AB, CD, and EF). The polypeptide chain of a TthHB27APRT subunit contains 178 amino acid residues forming ten beta strands and four alpha helices.

General Information

General Information Comment Organism
evolution Thermus thermophilus strain HB27 enzyme TthHB27APRT belongs to the type I phosphoribosyltransferases. These share the alpha/beta type folding of the polypeptide chain and the presence of a specific sequence of 13 amino acid residues involved in binding of diphosphate (PRPP-binding motif), together with a structurally variable subdomain (the so-called, hood domain) involved in base recognition Thermus thermophilus
metabolism type I phosphoribosyltransferases play an important role in common and salvage pathways of purine, pyrimidine, and pyrimidine coenzyme synthesis, as well as biosynthesis of histidine and tryptophan in lower organisms Thermus thermophilus
