Protein attributes

Sequence length	284 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Catalytic activity	ATP + D-ribose 5-phosphate = AMP + 5-phospho-alpha-D-ribose 1-diphosphate. HAMAP MF_00583_A
Cofactor	Binds 1 magnesium ion per subunit By similarity. HAMAP MF_00583_A
Pathway	Metabolic intermediate biosynthesis; 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis; 5-phospho-alpha-D-ribose 1-diphosphate from D-ribose 5-phosphate (route I): step 1/1. HAMAP MF_00583_A
Subcellular location	Cytoplasm By similarity HAMAP MF_00583_A.
Sequence similarities	Belongs to the ribose-phosphate pyrophosphokinase family.
Sequence caution	The sequence AAB99374.1 differs from that shown. Reason: Erroneous initiation.
