3.1.3.109

Accepted name:

ribulose-1,5-bisphosphate 5-phosphatase

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.
