Protein attributes

Sequence length	412 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Catalytic activity	ATP + 5-phospho-D-ribosylamine + glycine = ADP + phosphate + N(1)-(5-phospho-D-ribosyl)glycinamide. HAMAP-Rule MF_00138
Cofactor	Binds 1 magnesium or manganese ion per subunit By similarity.
Pathway	Purine metabolism; IMP biosynthesis via de novo pathway; N(1)-(5-phospho-D-ribosyl)glycinamide from 5-phospho-alpha-D-ribose 1-diphosphate: step 2/2. HAMAP-Rule MF_00138
Sequence similarities	Belongs to the GARS family. Contains 1 ATP-grasp domain.
Sequence caution	The sequence AAK05611.1 differs from that shown. Reason: Erroneous initiation.
