DesII catalyzes the deamination of its biosynthetic substrate (i.e., TDP-4,6-dideoxy-3-keto-D-glucose), whereas it promotes an oxidative dehydrogenation reaction when the C4 amino group of the substrate is replaced by a hydroxyl group (i.e., TDP-D-quinovose).

Extracellular polysaccharides are major immunogenic components of the bacterial cell envelope. However, little is known about their biosynthesis in the genus Acinetobacter, which includes A. baumannii, an important nosocomial pathogen. Whether Acinetobacter sp. produce a capsule or a lipopolysaccharide carrying an O antigen or both is not resolved. To explore these issues, genes involved in the synthesis of complex polysaccharides were located in 10 complete A. baumannii genome sequences, and the function of each of their products was predicted via comparison to enzymes with a known function. The absence of a gene encoding a WaaL ligase, required to link the carbohydrate polymer to the lipid A-core oligosaccharide (lipooligosaccharide) forming lipopolysaccharide, suggests that only a capsule is produced. Nine distinct arrangements of a large capsule biosynthesis locus, designated KL1 to KL9, were found in the genomes. Three forms of a second, smaller variable locus, likely to be required for synthesis of the outer core of the lipid A-core moiety, were designated OCL1 to OCL3 and also annotated. Each K locus includes genes for capsule export as well as genes for synthesis of activated sugar precursors, and for glycosyltransfer, glycan modification and oligosaccharide repeat-unit processing. The K loci all include the export genes at one end and genes for synthesis of common sugar precursors at the other, with a highly variable region that includes the remaining genes in between. Five different capsule loci, KL2, KL6, KL7, KL8 and KL9 were detected in multiply antibiotic resistant isolates belonging to global clone 2, and two other loci, KL1 and KL4, in global clone 1. This indicates that this region is being substituted repeatedly in multiply antibiotic resistant isolates from these clones.

The (D)methylmalonyl-CoA is isomerized to succinyl-CoA by Note that this reaction is also used for the degradation of hydrocarbon side chains of the amino acids valine, leucine, and isoleucine; (S)-methylmalonyl is the same as L-methylmalonyl; from KEGG pathway ) Similarly, unsaturated fatty acids need special enzymes to provide the beta oxidation intermediate trans-D2-enoyl-CoA, the substrate of .

AB - X-linked sideroblastic anemia is due to a deficiency of the erythroid form of the first enzyme in the heme biosynthetic pathway, 5-aminolevulinic acid synthase. Characteristics of the disease are variable, but typically include adult onset anemia, ineffective erythropoiesis with formation of ring sideroblasts, iron accumulation and pyridoxine responsiveness. Porphyrias are metabolic disorders due to deficiencies of other enzymes of this pathway, and are associated with striking accumulations and excess excretion of heme pathway intermediates and their oxidized products. Symptoms and signs of the porphyrias are almost all due to effects on the nervous system or skin. The three most common porphyrias, acute intermittent porphyria, porphyria cutanea tarda and erythropoietic protoporphyria, differ considerably from each other. The first presents with acute neurovisceral symptoms and can be aggravated by some drugs, hormones and nutritional changes, and is treated with intravenous heme and carbohydrate loading. The skin is affected in the latter two although the lesions are usually distinct and treatment is different. Porphyrias are more often manifest in adults than are most metabolic diseases. All porphyrias are inherited, with the exception of porphyria cutanea tarda, which is due to an acquired enzyme deficiency in liver, although an inherited deficiency is a predisposing factor in some cases.
Introduction to Biosynthesis and Pharmacognosy.
Carbohydrates (such as sugars, glycans and polysachharides) provide the largest biomass on Earth and are central to many aspects of biotechnology. As such glycoscience and glycobiotechnology have broad applications in the development of biofuels, biomaterials and food stuffs from recycled and readily available biomass, as well as in medical research. Through investigation of the chemistry, structure and interactions associated with various carbohydrate molecules, it is possible to understand mechanisms of disease, develop novel glyco-based therapeutics and replicate the natural biosynthesis of glycans for synthetic purposes. However, the complex and diverse molecular nature of carbohydrates means that there is an urgent need to develop robust, wide-ranging synthetic and analytical methodologies for general use in this area.
