CC   -!- FUNCTION: Catalyzes diesterification of phthiocerol, phthiodiolone, and
CC       phenolphthiocerol with mycocerosic acids, the final step in the
CC       phthiocerol, phthiodiolone and phenolphthiocerol dimycocerosate esters
CC       (PDIM) synthesis. Can directly transfer the mycocerosate bound to the
CC       mycocerosic acid synthase (mas) onto the substrate alcohols.
CC       {ECO:0000250|UniProtKB:P9WIN5}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 a mycocerosyl-[mycocerosic acid synthase] + a phthiocerol =
CC         a dimycocerosyl phthiocerol + 2 holo-[mycocerosic acid synthase].;
CC         EC=2.3.1.282; Evidence={ECO:0000250|UniProtKB:P9WIN5};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 a mycocerosyl-[mycocerosic acid synthase] + a phthiodiolone
CC         = a dimycocerosyl phthiodiolone + 2 holo-[mycocerosic acid
CC         synthase].; EC=2.3.1.282; Evidence={ECO:0000250|UniProtKB:P9WIN5};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 a mycocerosyl-[mycocerosic acid synthase] + a
CC         phenolphthiocerol = a dimycocerosyl phenolphthiocerol + 2 holo-
CC         [mycocerosic acid synthase].; EC=2.3.1.282;
CC         Evidence={ECO:0000250|UniProtKB:P9WIN5};
CC   -!- SUBUNIT: Monomer. Interacts directly with the acyl carrier protein
CC       (ACP) domain of the mycocerosic acid synthase (mas) protein.
CC       {ECO:0000250|UniProtKB:P9WIN5}.
CC   -!- DOMAIN: Consists of two structural domains that are related to each
CC       other. {ECO:0000250|UniProtKB:P9WIN5}.
CC   -!- SIMILARITY: Belongs to the acyltransferase PapA5 family. {ECO:0000305}.
