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.

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.
