Lysine N-acetyltransferase MbtK; Acyltransferase required for the direct transfer of medium- to long-chain fatty acyl moieties from a carrier protein (MbtL) on to the epsilon-amino group of lysine residue in the mycobactin core.

Electron transfer flavoprotein subunit beta; The electron transfer flavoprotein serves as a specific electron acceptor for other dehydrogenases. It transfers the electrons to the main respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase) (By similarity).

Electron transfer flavoprotein subunit alpha; The electron transfer flavoprotein serves as a specific electron acceptor for other dehydrogenases. It transfers the electrons to the main respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase) (By similarity).

Probable acyl-CoA dehydrogenase FadE27; Involved in the first cycle of side chain dehydrogenation in the beta-oxidation of cholesterol catabolism. It contributes partly to the virulence by increasing the efficiency of beta-oxidation. Catalyzes the dehydrogenation of acyl-CoA ester side chains of (25S)-3-oxo-cholest-4-en-26-oyl-CoA (3-OCS-CoA) to yield (24E)-3-oxo-cholest-4,24-dien-26-oyl-CoA. Also able to dehydrogenate steroyl-CoA such as 3-oxo- chol-4-en-24-oyl-CoA (3-OCO-CoA) as well as 3-oxo-4-pregnene-20- carboxyl-CoA (3-OPC-CoA). It dehydrogenates only (25S)-OCS-CoA diastereomer.
