Crystal Structure of mycolic acid cyclopropane synthase CmaA1 complexed with SAH and DDDMABCrystal Structure of mycolic acid cyclopropane synthase CmaA1 complexed with SAH and DDDMAB
Structural highlights
1kph is a 4 chain structure with sequence from Mycobacterium tuberculosis. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
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]
