Protein
Ribose 1,5-bisphosphate isomerase
Organism
Pyrococcus furiosus (strain ATCC 43587 / DSM 3638 / JCM 8422 / Vc1)
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 (By similarity).
Similarity
Belongs to the eIF-2B alpha/beta/delta subunits family. R15P isomerase subfamily.
