The biosynthesis of a enterobacterial common antigen can begin with a di-trans,octa-cis-undecaprenyl phosphate interacts with a Uridine diphosphate-N-acetylglucosamine through undecaprenyl-phosphate α-N-acetylglucosaminyl transferase resulting in a N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol and a Uridine 5'-monophosphate. The N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol then reacts with an UDP-ManNAcA from the Amino sugar and nucleotide sugar metabolism pathway. This reaction is metabolized by a UDP-N-acetyl-D-mannosaminuronic acid transferase resulting in a uridine 5' diphosphate, a hydrogen ion and a Undecaprenyl N-acetyl-glucosaminyl-N-acetyl-mannosaminuronate-4-acetamido-4,6-dideoxy-D-galactose pyrophosphate. Glucose 1 phosphate can be metabolize by interacting with a hydrogen ion and a thymidine 5-triphosphate by either reacting with a dTDP-glucose pyrophosphorylase or a dTDP-glucose pyrophosphorylase 2 resulting in the release of a pyrophosphate and a dTDP-D-glucose. The latter compound is then dehydrated through an dTDP-glucose 4,6-dehydratase 2 resulting in water and dTDP-4-dehydro-6-deoxy-D-glucose. The latter compound interacts with L-glutamic acid through a dTDP-4-dehydro-6-deoxy-D-glucose transaminase resulting in the release of oxoglutaric acid and dTDP-thomosamine. The latter compound interacts with acetyl-coa through a dTDP-fucosamine acetyltransferase resulting in a Coenzyme A, a hydrogen Ion and a TDP-Fuc4NAc. Undecaprenyl N-acetyl-glucosaminyl-N-acetyl-mannosaminuronate-4-acetamido-4,6-dideoxy-D-galactose pyrophosphate then interacts with a TDP--Fuc4NAc through a 4-acetamido-4,6-dideoxy-D-galactose transferase resulting in a hydrogen ion, a dTDP and a Undecaprenyl N-acetyl-glucosaminyl-N-acetyl-mannosaminuronate-4-acetamido-4,6-dideoxy-D-galactose pyrophosphate. This compound is then transported through a protein wzxE into the periplasmic space so that it can be incorporated into the outer membrane.
