Methylibium petroleiphilum (strain ATCC BAA-1232 / LMG 22953 / PM1)
FAMILY
DESCRIPTION
Also known as HIS1_METPP, hisG. 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. Heteromultimer composed of HisG and HisZ subunits.
