Common NamedTDP-beta-L-rhamnose
DescriptionDeoxythymidine diphosphate-L-rhamnose (dTDP-L-rhamnose) is the precursor of L-rhamnose, a saccharide required for the virulence of some pathogenic bacteria. In gram-negative bacteria such as Salmonella enterica, Vibrio cholerae, or Escherichia coli 075:K5, L-rhamnose is an important residue in the O-antigen of lipopolysaccharides, which are essential for resistance to serum killing and colonization. In gram-positive bacteria such as streptococci, the capsule is a recognized virulence factor. For example, L-rhamnose is known to be present in the capsule of Streptococcus suis, a causative agent of meningitis in humans. In Streptococcus mutans, L-rhamnose containing polysaccharides have been implicated in tooth surface colonization and adherence to kidney, muscle, and heart tissues. In mycobacteria, L-rhamnose is fundamental to the structural integrity of the cell wall since it connects the inner peptidoglycan layer to the arabinogalactan polysaccharides. dTDP-L-rhamnose is synthesized from glucose-1-phosphate and deoxythymidine triphosphate (dTTP) via a pathway involving four distinct enzymes. Whereas common sugars such as glucose, fructose, and mannose are all D-configured, bacteria commonly utilize the L-configured carbohydrates in pharmacologically active compounds and their cell-wall structures. The bacterial cell wall is unique to bacteria; neither the cell wall nor the enzymes and chemical intermediates in its formation have analogues in humans. The enzymes involved in dTDP-L-rhamnose synthesis are potential targets for the design of new therapeutic agents (PMID: 10802738 , 12773151 ).
