In enzymology a [3-methyl-2-oxobutanoate dehydrogenase (acetyl-transferring)] (EC 2.7.11.4) is an enzyme that catalyzes the chemical reactionATP + [3-methyl-2-oxobutanoate dehydrogenase (acetyl-transferring)] ADP + [3-methyl-2-oxobutanoate dehydrogenase (acetyl-transferring)] phosphateThus the two substrates of this enzyme are ATP and 3-methyl-2-oxobutanoate dehydrogenase (acetyl-transferring) whereas its 3 products are ADP 3-methyl-2-oxobutanoate dehydrogenase (acetyl-transferring) and phosphate.This enzyme belongs to the family of transferases specifically those transferring a phosphate group to the sidechain oxygen atom of serine or threonine residues in proteins (protein-serine/threonine kinases).
