Galacturonokinase (EC 2.7.1.44) is an enzyme that catalyzes the chemical reaction
The enzyme characterised from mung bean converts D-galacturonic acid to 1-phospho-α-D-galacturonic acid 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 an alcohol group as acceptor. The systematic name of this enzyme class is ATP:D-galacturonate 1-phosphotransferase. This enzyme is also called galacturonokinase (phosphorylating) D-galacturonic acid kinase. It participates in the metabolism of nucleotide sugars.[2]
