| + | [https://www.uniprot.org/uniprot/CMAS2_MYCTU CMAS2_MYCTU] Catalyzes the formation of trans cyclopropanated ketomycolate or methoxymycolate through the conversion of a double bond to a cyclopropane ring at the proximal position of an oxygenated mycolic acid via the transfer of a methylene group from S-adenosyl-L-methionine. In the absence of MmaA2, CmaA2 has a non-specific cis-cyclopropanating activity and is able to catalyze the conversion of a double bond to a cis cyclopropane ring at the distal position of an alpha mycolic acid. Cyclopropanated mycolic acids are key factors participating in cell envelope permeability, host immunomodulation and persistence.<ref>PMID:11092877</ref> <ref>PMID:7592990</ref> | ||
