This family contains O-succinylbenzoyl-CoA (OSB-CoA) synthetase (also known as O-succinylbenzoic acid CoA ligase) that belongs to the ANL superfamily and catalyzes the ligation of CoA to o-succinylbenzoate (OSB). It includes MenE in the bacterial menaquinone biosynthesis pathway which is a promising target for the development of novel antibacterial agents. MenE catalyzes CoA ligation via an acyl-adenylate intermediate; tight-binding inhibitors of MenE based on stable acyl-sulfonyladenosine analogs of this intermediate provide a pathway toward the development of optimized MenE inhibitors.
