Function

function

Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP.

Catalytic activity

Cofactor

Mg2+ (UniProtKB | Rhea| CHEBI:18420 )

Note: Binds 1 Mg2+ ion per subunit.

Pathway

Purine metabolism; AMP biosynthesis via de novo pathway; AMP from IMP: step 1/2.
