Mechanism Description	A FabI NAD+ triclosan ternary complex is formed by face-to-face interaction between the phenol ring of triclosan and the nicotinamide ring of NAD+ in the active site of FabI (enoyl-acyl carrier protein reductase) and therefore highly expressed reductases (narGHJI, garR, hcp and yeaA) and dehydrogenases (fdnGHI, ykgEF, garD, gldA and yeiQ) could bind triclosan which were as the NAD(P) cofactor, thus lowering the effective triclosan concentration.
