Abstract
|
Methyl transfer from the ubiquitous S-adenosyl-L-methionine (AdoMet) to either nitrogen, oxygen or carbon atoms is frequently employed in diverse organisms ranging from bacteria to plants and mammals. The reaction is catalyzed by methyltransferases (Mtases) and modifies DNA, RNA, proteins and small molecules, such as catechol for regulatory purposes. The various aspects of the role of DNA methylation in prokaryotic restriction-modification systems and in a number of cellular processes in eukaryotes including gene regulation and differentiation is well documented.
This entry represents cyclopropane-fatty-acyl-phospholipid synthase that is slosely related to methyltransferases.
Cyclopropane-fatty-acyl-phospholipid synthase or CFA synthase EC:2.1.1.79 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 tuberculosis contains two cis-cyclopropanes in the meromycolate chain. Cyclopropanation may contribute to the structural integrity of the cell wall complex [1].
