Protein
Cyclopropane mycolic acid synthase MmaA2
Organism
Mycobacterium tuberculosis (strain ATCC 25177 / H37Ra)
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.
Similarity
Belongs to the CFA/CMAS family.
