 115-179 3.35e-28

Nucleoside Triphosphate Pyrophosphohydrolase (EC 3.6.1.8) MazG-like domain found in Escherichia coli phosphoribosyl-ATP pyrophosphohydrolase (HisIE or PRATP-PH) and its homologs; This family includes Escherichia coli phosphoribosyl-ATP pyrophosphohydrolase, HisIE, and its homologs from all three kingdoms of life. E. coli HisIE is encoded by the hisIE gene, which is formed by hisE gene fused to hisl. HisIE is a bifunctional enzyme responsible for the second and third steps of the histidine-biosynthesis pathway. Its N-terminal and C-terminal domains have phosphoribosyl-AMP cyclohydrolase (HisI) and phosphoribosyl-ATP pyrophosphohydrolase (HisE or PRATP-PH) activity, respectively. This family corresponds to the C-terminal domain of HisIE and includes many hisE gene encoding proteins, all of which show significant sequence similarity to Mycobacterium tuberculosis phosphoribosyl-ATP pyrophosphohydrolase (HisE or PRATP-PH). These proteins may be responsible for only the second step in the histidine-biosynthetic pathway, irreversibly hydrolyzing phosphoribosyl-ATP (PRATP) to phosphoribosyl-AMP (PRAMP) and pyrophosphate.

Nucleoside Triphosphate Pyrophosphohydrolase (EC 3.6.1.8) MazG-like domain found in Escherichia coli phosphoribosyl-ATP pyrophosphohydrolase (HisIE or PRATP-PH) and its homologs; This family includes Escherichia coli phosphoribosyl-ATP pyrophosphohydrolase, HisIE, and its homologs from all three kingdoms of life. E. coli HisIE is encoded by the hisIE gene, which is formed by hisE gene fused to hisl. HisIE is a bifunctional enzyme responsible for the second and third steps of the histidine-biosynthesis pathway. Its N-terminal and C-terminal domains have phosphoribosyl-AMP cyclohydrolase (HisI) and phosphoribosyl-ATP pyrophosphohydrolase (HisE or PRATP-PH) activity, respectively. This family corresponds to the C-terminal domain of HisIE and includes many hisE gene encoding proteins, all of which show significant sequence similarity to Mycobacterium tuberculosis phosphoribosyl-ATP pyrophosphohydrolase (HisE or PRATP-PH). These proteins may be responsible for only the second step in the histidine-biosynthetic pathway, irreversibly hydrolyzing phosphoribosyl-ATP (PRATP) to phosphoribosyl-AMP (PRAMP) and pyrophosphate.

Nucleoside Triphosphate Pyrophosphohydrolase (EC 3.6.1.8) MazG-like domain found in His4-like fungal histidine biosynthesis trifunctional proteins and their homologs; This family includes fungal histidine biosynthesis trifunctional proteins and their homologs from eukaryotes and bacteria. Some family members contain three domains responsible for phosphoribosyl-AMP cyclohydrolase (PRAMP-CH), phosphoribosyl-ATP pyrophosphohydrolase (PRATP-PH), and histidinol dehydrogenase (Histidinol-DH) activity, respectively. Some others do not have Histidinol-DH domain, but have an additional N-terminal TIM phosphate binding domain. This family corresponds to the domain for PRATP-PH activity, which shows significant sequence similarity to Mycobacterium tuberculosis PRATP-PH that catalyzes the second step in the histidine-biosynthetic pathway, irreversibly hydrolyzing phosphoribosyl-ATP (PRATP) to phosphoribosyl-AMP (PRAMP) and pyrophosphate.

Nucleoside Triphosphate Pyrophosphohydrolase (EC 3.6.1.8) MazG-like domain found in Mycobacterium tuberculosis phosphoribosyl-ATP pyrophosphohydrolase (HisE or PRATP-PH) and its bacterial homologs; This family includes M. tuberculosis phosphoribosyl-ATP pyrophosphohydrolase (HisE or PRATP-PH) and its bacterial homologs. M. tuberculosis HisE is encoded by the hisE gene, which is a separate gene presenting in many bacteria and archaea but is fused to hisI in other bacteria, fungi and plants. HisE is responsible for the second step in the histidine-biosynthetic pathway. It can irreversibly hydrolyze phosphoribosyl-ATP (PRATP) to phosphoribosyl-AMP (PRAMP) and pyrophosphate. HisE dimerizes into a four alpha-helix bundle, forming two inferred PRATP active sites on the outer faces. M. tuberculosis HisE has been found to be essential for growth in vitro, thus making it a potential drug target for tuberculosis.
