Sedoheptulose-bisphosphatase
Sedoheptulose-bisphosphatase (also sedoheptulose-1,7-bisphosphatase or SBPase) is an enzyme that catalyzes the removal of a phosphate group from sedoheptulose 1,7-bisphosphate to produce sedoheptulose 7-phosphate. SBPase is an example of a phosphatase, or, more generally, a hydrolase. This enzyme participates in the Calvin cycle.
