Structure and biosynthesis

The components of vibriobactin are three 2,3-dihydroxybenzoic acid (DHB), two threonine (Thr), and one norspermidine (NSPD). DHB is synthesized from chorismic acid by a series of enzymes: VibA, VibB, and VibC. DHB is linked to NSPD by VibE, VibB and VibH in order and forms DHB-NSPD.[2] On the other hand, DHB performs condensation and cyclization with Thr by VibE, VibB, and VibF to form the heterocyclic molecule linked on VibF: DHB-Thr-VibF. DHB-NSPD and DHB-Thr-VibF are then put together by VibF to form vibriobactin.[3]
