Function

CMAS1_MYCTU Catalyzes the conversion of a double bond to a cyclopropane ring at the distal position of an alpha mycolic acid via the transfer of a methylene group from S-adenosyl-L-methionine. Cyclopropanated mycolic acids are key factors participating in cell envelope permeability, host immunomodulation and persistence.[1]
