Type: | Family | Name: | Mycolic acid cyclopropane synthase |
Description: | This entry represents mycolic acid cyclopropane synthases and related enzymes, including CmaA1, CmaA2 (cyclopropane mycolic acid synthase A1 and A2) and MmaA1-4 (methoxymycolic acid synthase A1-4). All are thought to be S-adenosyl-L-methionine (SAM) utilising methyltransferases [].Mycolic acid cyclopropane synthase or cyclopropane-fatty-acyl-phospholipid synthase (CFA synthase) catalyses the reaction: S-adenosyl-L-methionine + phospholipid olefinic fatty acid ->S-adenosyl-L-homocysteine + phospholipid cyclopropane fatty acid. The major mycolic acid produced by Mycobacterium tuberculosiscontains two cis-cyclopropanes in the meromycolate chain. Cyclopropanation may contribute to the structural integrity of the cell wall complex []. | Short Name: | Mycolic_cyclopropane_synthase |
