Comments [?]

Function Catalyzes the conversion of AMP and phosphate to adenine and ribose 1,5-bisphosphate (R15P). Exhibits phosphorylase activity toward CMP and UMP in addition to AMP. Functions in an archaeal AMP degradation pathway, together with R15P isomerase and RubisCO.
Catalytic activity RHEA:36975: AMP + phosphate = adenine + alpha-D-ribose 1,5-bisphosphate
EC 2.4.2.57
RHEA:36987: CMP + phosphate = alpha-D-ribose 1,5-bisphosphate + cytosine
EC 2.4.2.57
RHEA:36991: phosphate + UMP = alpha-D-ribose 1,5-bisphosphate + uracil
EC 2.4.2.57
Similarity Belongs to the thymidine/pyrimidine-nucleoside phosphorylase family. Type 2 subfamily.
