ID 1.3.8.3 DE (R)-benzylsuccinyl-CoA dehydrogenase. CA (R)-2-benzylsuccinyl-CoA + H(+) + oxidized [electron-transfer CA flavoprotein] = (E)-2-benzylidenesuccinyl-CoA + reduced [electron- CA transfer flavoprotein]. CC -!- Contains a tightly-bound FAD cofactor. CC -!- Unlike other acyl-CoA dehydrogenases, this enzyme exhibits high CC substrate- and enantiomer specificity; it is highly specific for (R)- CC benzylsuccinyl-CoA and is inhibited by (S)-benzylsuccinyl-CoA. CC -!- Forms the third step in the anaerobic toluene metabolic pathway in CC Thauera aromatica. CC -!- Ferricenium ion is an effective artificial electron acceptor. CC -!- Formerly EC 1.3.99.21.
