phosphomannomutase
AlgC: phosphomannomutase, (RmlA, EC 2.7.7.24): glucose-1-phosphate thymidylyltransferase catalyzes the conversion of thymidylmonophosphate nucleotide to glucose-1-phosphate, (RmlB, EC 4.2.1.46): dTDP-D-glucose 4,6-dehydratase which catalyzes an oxidation of the C4 hydroxyl group of the D-glucose residue, then dehydration, ending to the formation of dTDP-4-oxo-6-deoxyl-D-glucose, (RmlC, EC 5.1.3.13) :dTDP-4-dehy-drorhamnose 3,5-epimerase which catalyzes a double epimerization reaction at the C3 and C5 positions of the 4-oxo-6-deoxyl-D-glucose ring, (RmlD, EC 1.1.1.133): dTDP-4-dehydrorhamnose reductase which reduces the C4 keto group of the 4-oxo-6-deoxyl-L-mannose moiety and leads to the formation of dTDP-L-rhamnose, FabD: malonyl-CoA:ACP transacylase, FabB, FabH, and FabF: β-ketoacyl-ACP synthetases, FabG: NADPH-dependent β-ketoacyl-ACP reductase, FabA, FabZ: β-hydroxyacyl-ACP dehydratases, FabI: The NADH-dependent enoyl-ACP reductase, HAA: 3-(3-hydroxyalkanoyloxy)alkanoic acid,: RhlA: 3-(3-hydroxyalkanoyloxy) alkanoate synthetases, RhlB: rhamnosyltransferase 1, and RhlC:rhamnosyltransferase 2. All required enzymatic steps are font bolded.
