Functioni

Catalyzes the synthesis of GMP from XMP.UniRule annotation

Catalytic activityi

ATP + XMP + L-glutamine + H2O = AMP + diphosphate + GMP + L-glutamate.UniRule annotation

Pathwayi: GMP biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes GMP from XMP (L-Gln route).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. GMP synthase [glutamine-hydrolyzing] subunit A (guaAA), GMP synthase [glutamine-hydrolyzing] subunit B (guaAB)
This subpathway is part of the pathway GMP biosynthesis, which is itself part of Purine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes GMP from XMP (L-Gln route), the pathway GMP biosynthesis and in Purine metabolism.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
