chemical reaction A chemical reaction is a process that leads to the chemistry, chemical transformation of one set of chemical substances to another. When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an Gibbs free energy, ...

:ATP + cetyl-CoA carboxylase

\rightleftharpoons

ADP + cetyl-CoA carboxylasephosphate Thus, the two substrates of this enzyme are ATP and acetyl-CoA carboxylase, whereas its two products are ADP and acetyl-CoA carboxylase phosphate. This enzyme belongs to the family of transferases, specifically those transferring a phosphate group to the sidechain

oxygen Oxygen is a chemical element; it has chemical symbol, symbol O and atomic number 8. It is a member of the chalcogen group (periodic table), group in the periodic table, a highly reactivity (chemistry), reactive nonmetal (chemistry), non ...

of this enzyme class is ATP: cetyl-CoA carboxylasephosphotransferase. Other names in common use include acetyl coenzyme A carboxylase kinase (phosphorylating), acetyl-CoA carboxylase bound kinase, acetyl-CoA carboxylase kinase, acetyl-CoA carboxylase kinase (cAMP-independent), acetyl-CoA carboxylase kinase 2, acetyl-CoA carboxylase kinase-2, acetyl-CoA carboxylase kinase-3 (AMP-activated), acetyl-coenzyme A carboxylase kinase, ACK2, ACK3, AMPK, I-peptide kinase, and STK5.
