Mtb Pks5 (a mas homolog) synthesizes multimethylated mycocerosic acids. This protein acts on long-chain fatty acids adenylate esters (LCFA adenylate esters) in the LCFA adenylate ester:Pks5 complex by incorporating methylmalonyl residues, to form tri- or tetra-methylated branched fatty acids (mycocerosyl) (Roussau et al. 2003; Trivedi et al. 2005).
