comments
This enzyme is Dihydrolipoyllysine-residue acetyltransferase, E2 component of pyruvate dehydrogenase complex.
The pyruvate dehydrogenase complex is composed of pyruvate dehydrogenaes (E1 component; E.C. 1.2.4.1), dihydrolipoyllysine S-acetyltransferase (E2 component; E.C. 2.3.1.12), and lipoamide dehydrogenase (E3 component; E.C. 1.8.1.4). (The E3 component corresponds to the entry T00017 in EzCatDB.)
This enzyme is composed of the N-terminal lipoyl-binding domain, E3-binding domain, and the C-terminal catalytic domain.
This enzyme catalyzes transfer of acetyl group from lypoyllysine of the lipoyl-binding domain to thiol group of CoA.
The catalytic domain of this enzyme is homologous to that of dihydrolipoamide succinyltransferase (E.C. 2.3.1.61; T00223 in EzCatDB). The catalytic residues seem to be conserved between these two enzymes. Thus, the catalytic mechanism must be the same as that of the homologue.
