Reaction: D-ribulose-1,5-bisphosphate + H2O = D-ribulose 1-phosphate + phosphate
Other name(s): RuBP 5-phosphatase
Systematic name: D-ribulose-1,5-bisphosphate 5-phosphohydrolase
Comments: The enzyme, characterized from the halophilic archaeon Halopiger xanaduensis, participates in a non-carboxylating pentose bisphosphate pathway for nucleoside degradation, which is found in some halophilic archaea. The enzyme requires both monovalent and divalent ions for optimal activity.
