CC   -!- FUNCTION: Acyl-CoA-dependent acyltransferase; part of the gene cluster
CC       that mediates the biosynthesis of mannosylerythritol lipids (MELs),
CC       surface-active substances that enhance the availability of water-
CC       insoluble substrates (Probable) (PubMed:20564650, PubMed:31923270).
CC       Depending on the number of acetyl groups, mannosylerythritol lipids can
CC       be differentiated into MEL A (fully acetylated), MEL B and MEL C
CC       (monoacetylated at R-6 and R-4, respectively), and the fully
CC       deacetylated MEL D (By similarity). The first step in the pathway is
CC       the generation of mannosylerythritol by the glycosyltransferase EMT1
CC       which catalyzes the transfer of GDP-mannose to the C-4 atom of meso-
CC       erythritol (Probable). This reaction has to be stereospecific, since
CC       only mannosyl-D-erythritol is generated (Probable). The produced
CC       disaccharide is subsequently acylated with fatty acids of various
CC       lengths by the acyltransferases MAC1 and MAC2 at positions C-2 and C-3,
CC       repectively (Probable). The existence of MEL derivatives which carry an
CC       acetyl group at C-2 implies that at least MAC1 also accepts acetyl-CoA
CC       as a donor (Probable). The final step of MEL biosynthesis is the
CC       acetylation of the fully acylated mannosylerythritol lipids catalyzed
CC       by the acetyl-CoA-dependent acetyltransferase MAT1 (Probable). MAT1
CC       displays a relaxed regioselectivity and is able to transfer
CC       acetylgroups to both positions C-4 and C-6 of the mannosyl moiety
CC       (Probable). {ECO:0000250|UniProtKB:A0A0D1E3S6,
CC       ECO:0000269|PubMed:20564650, ECO:0000269|PubMed:31923270,
CC       ECO:0000305|PubMed:23558529, ECO:0000305|PubMed:31923270}.
CC   -!- PATHWAY: Secondary metabolite biosynthesis.
CC       {ECO:0000305|PubMed:31923270}.
CC   -!- INDUCTION: Expression is induced when cells are grown in cultures
CC       containing vegetable oil as the carbon source.
CC       {ECO:0000269|PubMed:31923270}.
CC   -!- BIOTECHNOLOGY: MELs not only have high potential as eco-friendly
CC       biosurfactants due to their excellent surface activity, but also have
CC       attracted considerable recent interest because of thei runique
CC       properties, including self-assembly, anti-tumor and cell
CC       differentiation induction activities, and moisturizing and hair-
CC       repairing properties. {ECO:0000269|PubMed:16233292,
CC       ECO:0000269|PubMed:17279642, ECO:0000269|PubMed:17428643,
CC       ECO:0000269|PubMed:19341364, ECO:0000269|Ref.6}.
CC   -!- SIMILARITY: Belongs to the trichothecene O-acetyltransferase family.
CC       {ECO:0000305}.
