Cofactor

Binds 1 magnesium ion per subunit By similarity. HAMAP MF_00011

Pathway

Purine metabolism; AMP biosynthesis via de novo pathway; AMP from IMP: step 1/2. HAMAP MF_00011

Subunit structure

Homodimer By similarity. HAMAP MF_00011

Subcellular location

Cytoplasm By similarity HAMAP MF_00011.
