hisG2

Gene
hisG2
Protein
ATP phosphoribosyltransferase 2
Organism
Geobacter sulfurreducens (strain ATCC 51573 / DSM 12127 / PCA)
Length
212 amino acids
Function
Catalyzes the condensation of ATP and 5-phosphoribose 1-diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity (By similarity).
Similarity
Belongs to the ATP phosphoribosyltransferase family. Short subfamily.
Mass
23.98 kDa
