B1YEG7 · UPP_EXIS2

Function

function

Catalyzes the conversion of uracil and 5-phospho-alpha-D-ribose 1-diphosphate (PRPP) to UMP and diphosphate.

Catalytic activity

Cofactor

Mg2+ (UniProtKB | Rhea| CHEBI:18420 )

Note: Binds 1 Mg2+ ion per subunit. The magnesium is bound as Mg-PRPP.

Activity regulation

Allosterically activated by GTP.

Pathway

Pyrimidine metabolism; UMP biosynthesis via salvage pathway; UMP from uracil: step 1/1.
