General annotation (Comments)

Function	Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis By similarity.
Catalytic activity	AMP + diphosphate = adenine + 5-phospho-alpha-D-ribose 1-diphosphate. HAMAP MF_00004
Pathway	Purine metabolism; AMP biosynthesis via salvage pathway; AMP from adenine: step 1/1. HAMAP MF_00004
Subunit structure	Homodimer By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the purine/pyrimidine phosphoribosyltransferase family.
