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

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
