phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase, eukaryotic type; This enzyme acts in the biosynthesis of histidine and has been characterized in S. cerevisiae and Arabidopsis where it complements the E. coli HisA gene. In eukaryotes the gene is known as HIS6. In bacteria, this gene is found in Fibrobacter succinogenes, presumably due to lateral gene transfer from plants in the rumen gut.

Phosphoribosylformimino-5-aminoimidazole carboxamide ribonucleotide (ProFAR) isomerase (HisA) and the cyclase subunit of imidazoleglycerol phosphate synthase (HisF). The ProFAR isomerase catalyzes the fourth step in histidine biosynthesis, an isomerisation of the aminoaldose moiety of ProFAR to the aminoketose of PRFAR (N-(5'-phospho-D-1'-ribulosylformimino)-5-amino-1-(5''-phospho-ribosyl)-4-imidazolecarboxamide). In bacteria and archaea, ProFAR isomerase is encoded by the HisA gene. The Imidazole glycerol phosphate synthase (IGPS) catalyzes the fifth step of histidine biosynthesis, the formation of the imidazole ring. IGPS converts N1-(5'-phosphoribulosyl)-formimino-5-aminoimidazole-4-carboxamide ribonucleotide (PRFAR) to imidazole glycerol phosphate (ImGP) and 5'-(5-aminoimidazole-4-carboxamide) ribonucleotide (AICAR). This conversion involves two tightly coupled reactions in distinct active sites of IGPS. The two catalytic domains can be fused, like in fungi and plants, or peformed by a heterodimer (HisH-glutaminase and HisF-cyclase), like in bacteria.

Histidine biosynthesis protein; Proteins involved in steps 4 and 6 of the histidine biosynthesis pathway are contained in this family. Histidine is formed by several complex and distinct biochemical reactions catalyzed by eight enzymes. The enzymes in this Pfam entry are called His6 and His7 in eukaryotes and HisA and HisF in prokaryotes. The structure of HisA is known to be a TIM barrel fold. In some archaeal HisA proteins the TIM barrel is composed of two tandem repeats of a half barrel. This family belong to the common phosphate binding site TIM barrel family.

phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; This protein family consists of HisA, phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase, the enzyme catalyzing the fourth step in histidine biosynthesis. It is closely related to the enzyme HisF for the sixth step. Examples of this enzyme in Actinobacteria have been found to be bifunctional, also possessing phosphoribosylanthranilate isomerase activity; the trusted cutoff here has now been raised to 275.0 to exclude the bifunctional group, now represented by model TIGR01919. HisA from Lactococcus lactis was reported to be inactive (MEDLINE:93322317). [Amino acid biosynthesis, Histidine family]
