Q9KSM8 · PURT_VIBCH

Function

function

Involved in the de novo purine biosynthesis. Catalyzes the transfer of formate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR). Formate is provided by PurU via hydrolysis of 10-formyl-tetrahydrofolate.

Catalytic activity

Pathway

Purine metabolism; IMP biosynthesis via de novo pathway; N2-formyl-N1-(5-phospho-D-ribosyl)glycinamide from N1-(5-phospho-D-ribosyl)glycinamide (formate route): step 1/1.
