Protein attributes

Sequence length	333 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Catalytic activity	ATP + 2-(formamido)-N(1)-(5-phospho-D-ribosyl)acetamidine = ADP + phosphate + 5-amino-1-(5-phospho-D-ribosyl)imidazole. HAMAP MF_00741_A
Pathway	Purine metabolism; IMP biosynthesis via de novo pathway; 5-amino-1-(5-phospho-D-ribosyl)imidazole from N(2)-formyl-N(1)-(5-phospho-D-ribosyl)glycinamide: step 2/2. HAMAP MF_00741_A
Subcellular location	Cytoplasm By similarity HAMAP MF_00741_A.
Sequence similarities	Belongs to the AIR synthase family.
Sequence caution	The sequence AAM31112.1 differs from that shown. Reason: Erroneous initiation.
