This protein is involved in step 2 of the subpathway that synthesizes N(1)-(5-phospho-D-ribosyl)glycinamide from 5-phospho-alpha-D-ribose 1-diphosphate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Amidophosphoribosyltransferase (purF)
  2. Phosphoribosylamine--glycine ligase (purD)
This subpathway is part of the pathway IMP biosynthesis via de novo pathway, which is itself part of Purine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes N(1)-(5-phospho-D-ribosyl)glycinamide from 5-phospho-alpha-D-ribose 1-diphosphate, the pathway IMP biosynthesis via de novo pathway and in Purine metabolism.

<p>The checksum is a form of redundancy check that is calculated from the sequence.
