Once in the cytoplasm, MurNac and water undergo a reversible reaction through a N-acetylmuramic acid 6-phosphate etherase, producing a D-lactic acid and N-Acetyl-D-Glucosamine 6-phosphate. This latter compound can also be introduced into the cytoplasm through a phosphorylating PTS permase in the inner membrane that allows for the transport of N-Acetyl-D-glucosamine from the periplasmic space. N-Acetyl-D-Glucosamine 6-phosphate can also be obtained from chitin dependent reactions. Chitin is hydrated through a bifunctional chitinase to produce chitobiose. This in turn gets hydrated by a beta-hexosaminidase to produce N-acetyl-D-glucosamine. The latter undergoes an atp dependent phosphorylation leading to the production of N-Acetyl-D-Glucosamine 6-phosphate.
N-Acetyl-D-Glucosamine 6-phosphate is then be deacetylated in order to produce Glucosamine 6-phosphate through a N-acetylglucosamine-6-phosphate deacetylase. This compound is then deaminased into Beta-D-fructofuranose 6-phosphate through a glucosamine-6-phosphate deaminase.
Beta-D-fructofuranose 6-phosphate is isomerized into a beta-D-glucose 6-phosphate through a glucose-6-phosphate isomerase. The compound is then isomerized by a putative beta-phosphoglucomutase to produce a beta-D-glucose 1-phosphate. This compound enters the nucleotide sugar metabolism through uridylation resulting in a UDP-glucose. UDP-glucose is then dehydrated through a UDP-glucose 6-dehydrogenase to produce a UDP-glucuronic acid. This compound undergoes a NAD dependent reaction through a bifunctional polymyxin resistance protein to produce UDP-Beta-L-threo-pentapyranos-4-ulose. This compound then reacts with L-glutamic acid through a UDP-4-amino-4-deoxy-L-arabinose--oxoglutarate aminotransferase to produce an oxoglutaric acid and UDP-4-amino-4-deoxy-beta-L-arabinopyranose
The latter compound interacts with a N10-formyl-tetrahydrofolate through a bifunctional polymyxin resistance protein ArnA, resulting in a tetrahydrofolate, a hydrogen ion and a UDP-4-deoxy-4-formamido-beta-L-arabinopyranose, which in turn reacts with a product of the methylerythritol phosphate and polysoprenoid biosynthesis pathway, di-trans,octa-cis-undecaprenyl phosphate to produce a 4-deoxy-4-formamido-alpha-L-arabinopyranosyl ditrans, octacis-undecaprenyl phosphate.
Alpha-D-glucose is introduced into the cytoplasm through a glucose PTS permease, which phosphorylates the compound in order to produce an alpha-D-glucose 6-phosphate. This compound is then modified through a phosphoglucomutase 1 to yield alpha-D-glucose 1-phosphate. This compound can either be adenylated to produce ADP-glucose or uridylylated to produce galactose 1-phosphate through glucose-1-phosphate adenyllyltransferase and galactose-1-phosphate uridylyltransferase respectively.PW000895Metabolicpolymyxin resistanceUDP-glucuronic acid compound undergoes a NAD dependent reaction through a bifunctional polymyxin resistance protein to produce UDP-Beta-L-threo-pentapyranos-4-ulose.
