Comments [?]

Function Catalyzes the isomerization of ribose 1,5-bisphosphate (R15P) to ribulose 1,5-bisphosphate (RuBP), the CO(2) acceptor and substrate for RubisCO. Functions in an archaeal AMP degradation pathway, together with AMP phosphorylase and RubisCO.
Catalytic activity RHEA:32243: alpha-D-ribose 1,5-bisphosphate = D-ribulose 1,5-bisphosphate
EC 5.3.1.29
Miscellaneous Reaction proceeds via a cis-phosphoenolate intermediate.
Similarity Belongs to the eIF-2B alpha/beta/delta subunits family. R15P isomerase subfamily.
