Function
function
Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'-phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'-phosphate.
Catalytic activity
- 2,5-diamino-6-hydroxy-4-(5-phosphoribosylamino)-pyrimidine + H2O + H+ = 5-amino-6-(5-phospho-D-ribosylamino)uracil + NH4+
Cofactor
Note: Binds 1 zinc ion.
Pathway
Cofactor biosynthesis; riboflavin biosynthesis; 5-amino-6-(D-ribitylamino)uracil from GTP: step 2/4.
