Functions
cyclopropane-fatty-acyl-phospholipid synthase activity/methyltransferase activity
Processes
mycolic acid biosynthetic process
Components
cell wall/plasma membrane
General Function
Methyltransferase activity
Specific Function
Catalyzes the conversion of a double bond to a cis cyclopropane ring at the distal position of an alpha mycolic acid via the transfer of a methylene group from S-adenosyl-L-methionine. MmaA2 also catalyzes the biosynthesis of the cis-cyclopropanated methoxymycolates. Cyclopropanated mycolic acids are key factors participating in cell envelope permeability, host immunomodulation and persistence.
