Metabolite Identification
Common Name3-deoxy-D-manno-2-octulosonate
Description3-deoxy-D-manno-2-octulosonate is a carbohydrate metabolite classified as a 2-keto sugar derivative. It plays a crucial role in various biosynthetic pathways, particularly in the synthesis of polysaccharides such as rhamnogalacturonan II in plants, where it is activated by the enzyme CTP:3-deoxy-D-manno-2-octulosonate cytidylyltransferase (CMP-KDO synthetase) (PMID:21893514 ). In bacteria, 3-deoxy-D-manno-2-octulosonate is involved in the synthesis of 3-deoxy-D-manno-2-octulosonate-8-phosphate (KDO8P), catalyzed by the enzyme KDO8P synthase, which condenses D-arabinose-5-phosphate (A5P) and phosphoenolpyruvate (PEP) to produce KDO8P and inorganic phosphate (PMID:19399763 ). Structural studies have revealed that KDO8P synthase forms a tetrameric complex, highlighting its intricate biochemical architecture (PMID:19399763 ). Additionally, KDO8P synthase and its homolog, DAH7PS, share a similar aldol-type condensation mechanism, making them potential targets for developing new anti-infectious agents (PMID:15721322 ). The enzyme's metal dependency varies across different organisms, indicating its versatile biochemical nature (PMID:15308670 ).
