Demethylmenaquinone Methyltransferase (MenG)

Target
MenG
Molecular classification
Enzyme, Methyltransferase
01

Overview

Demethylmenaquinone methyltransferase (MenG) is an enzyme that catalyzes the final step in the biosynthesis of menaquinone (vitamin K2) in bacteria. It transfers a methyl group from S-adenosyl-L-methionine (SAM) to demethylmenaquinone (DMK), producing menaquinone (MK). MenG is essential for bacterial respiration and energy production but is absent in humans, making it a promising target for antibacterial drug development.
