Protein Family Models

2-oxoglutarate dehydrogenase complex dihydrolipoyllysine-residue succinyltransferase is the E2 component of the 2-oxoglutarate dehydrogenase (OGDH) complex which catalyzes the second step in the conversion of 2-oxoglutarate to succinyl-CoA and CO(2)

This family represents a small domain of the E2 subunit of 2-oxo-acid dehydrogenases responsible for the binding of the E3 subunit. [1]. 8805537.

This family covers two Prosite entries, the conserved lysine residue binds biotin in one group and lipoic acid in the other. Note that the HMM does not currently recognise the Glycine cleavage system H proteins. (from Pfam)

This HMM describes the TCA cycle 2-oxoglutarate system E2 component, dihydrolipoamide succinyltransferase. It is closely related to the pyruvate dehydrogenase E2 component, dihydrolipoamide acetyltransferase. The seed for this model includes mitochondrial and Gram-negative bacterial forms. Mycobacterial candidates are highly derived, differ in having and extra copy of the lipoyl-binding domain at the N-terminus. They score below the trusted cutoff, but above the noise cutoff and above all examples of dihydrolipoamide acetyltransferase.
