Subcellular location

Subcellular Location:
Cytoplasm.

Function

Function:
Involved in the de novo synthesis of guanine nucleotides which are not only essential for DNA and RNA synthesis, but also provide GTP, which is involved in a number of cellular processes important for cell division.
Pathway:
Purine metabolism; GMP biosynthesis; GMP from XMP (L-Gln route): step 1/1.
Catalytic Activity:
ATP + XMP + L-glutamine + H(2)O = AMP + diphosphate + GMP + L-glutamate.
Active Site:
ACT_SITE 104 104 For GATase activity.
Cross Reference Drug Bank:
