2-237 1.23e-99

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]

1-234 1.64e-95

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]

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.

1-240 4.40e-33

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.

3-Keto-L-gulonate 6-phosphate decarboxylase (KGPDC) and D-arabino-3-hexulose-6-phosphate synthase (HPS). KGPDC catalyzes the formation of L-xylulose 5-phosphate and carbon dioxide from 3-keto-L-gulonate 6-phosphate as part of the anaerobic pathway for L-ascorbate utilization in some eubacteria. HPS catalyzes the formation of D-arabino-3-hexulose-6-phosphate from D-ribulose 5-phosphate and formaldehyde in microorganisms that can use formaldehyde as a carbon source. Both catalyze reactions that involve the Mg2+-assisted formation and stabilization of 1,2-enediolate reaction intermediates.

64-116 1.48e-03

N-acetylmannosamine-6-phosphate epimerase (NanE) converts N-acetylmannosamine-6-phosphate to N-acetylglucosamine-6-phosphate. This reaction is part of the pathway that allows the usage of sialic acid as a carbohydrate source. Sialic acids are a family of related sugars that are found as a component of glycoproteins, gangliosides, and other sialoglycoconjugates.

37-103 5.50e-03

TIM barrel proteins share a structurally conserved phosphate binding motif and in general share an eight beta/alpha closed barrel structure. Specific for this family is the conserved phosphate binding site at the edges of strands 7 and 8. The phosphate comes either from the substrate, as in the case of inosine monophosphate dehydrogenase (IMPDH), or from ribulose-5-phosphate 3-epimerase (RPE) or from cofactors, like FMN.
