Ribose 1,5-bisphosphate phosphokinase
From Wikipedia, the free encyclopedia
Ribose 1,5-bisphosphate phosphokinase (EC 2.7.4.23) is an enzyme that catalyzes the chemical reaction
The enzyme characterised from a mutant Escherichia coli converts D-ribose 1,5-bisphosphate to phosphoribosyl pyrophosphate by transferring a phosphate group from the cofactor, adenosine triphosphate (ATP), which is converted to adenosine diphosphate (ADP).[1]
This enzyme is a transferase, specifically one transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor. The systematic name of this enzyme class is ATP:ribose-1,5-bisphosphate phosphotransferase. Other names in common use include ribose 1,5-bisphosphokinase, and PhnN.[2]
