CC   -!- FUNCTION: Catalyzes the formation of trans cyclopropanated ketomycolate
CC       or methoxymycolate through the conversion of a double bond to a
CC       cyclopropane ring at the proximal position of an oxygenated mycolic
CC       acid via the transfer of a methylene group from S-adenosyl-L-
CC       methionine. In the absence of MmaA2, CmaA2 has a non-specific cis-
CC       cyclopropanating activity and is able to catalyze the conversion of a
CC       double bond to a cis cyclopropane ring at the distal position of an
CC       alpha mycolic acid. Cyclopropanated mycolic acids are key factors
CC       participating in cell envelope permeability, host immunomodulation and
CC       persistence (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=1-acyl-2-(9Z)-enoyl-sn-glycero-3-phospholipid + S-adenosyl-L-
CC         methionine = 1-acyl-2-(9-cyclopronane)-acyl-sn-glycero-3-phospholipid
CC         + H(+) + S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:11988,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC         ChEBI:CHEBI:76593, ChEBI:CHEBI:76594; EC=2.1.1.79;
CC   -!- PATHWAY: Lipid metabolism; mycolic acid biosynthesis.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the CFA/CMAS family. {ECO:0000305}.
