In enzymology, a butyrate kinase (EC 2.7.2.7) is an enzyme that catalyzes the chemical reaction
- ATP + butanoate
ADP + butanoyl phosphate
Thus, the two substrates of this enzyme are ATP and butanoate, whereas its two products are ADP and butanoyl phosphate.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a carboxy group as acceptor. The systematic name of this enzyme class is ATP:butanoate 1-phosphotransferase. This enzyme participates in butanoate metabolism.
Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1SAZ and 1X9J.
