after limited proteolysis of the dihydrolipoyl transacetylase component ( e2 ) of azotobacter vinelandii pyruvate dehydrogenase complex ( pdc ) , a c-terminal domain was obtained which retained the transacetylase active site and the quaternary structure of e2 but had lost the lipoyl-containing n-terminal part of the chain and the binding sites for the peripheral components , pyruvate dehydrogenase and lipoamide dehydrogenase .
