ATP phosphoribosyltransferase (medicine)


ATP phosphoribosyltransferase
<enzyme> An enzyme that catalyses the first step of the pathway for histidine biosynthesis in salmonella typhimurium. ATP reacts reversibly with 5-phosphoribosyl-1-pyrophosphate to yield n-1-(5'-phosphoribosyl)-ATP and pyrophosphate.

Chemical name: 1-(5-Phospho-D-ribosyl)-ATP:pyrophosphate phospho-alpha-D- ribosyltransferase

Registry number: EC 2.4.2.17
