Summary:
Although the deoxyhexose rhamnose is found in glycoconjugates of bacteria and plants (but not animals), the rare D-isoform is found only in the outer cell surface of bacteria. α-D-rhamnose is a constituent of the lipopolysaccharide of the plant pathogens Xanthomonas campestris and Pseudomonas syringae, and animal pathogens Pseudomonas aeruginosa, Burkholderia cepacia, Campylobacter fetus and Helicobacter pylori [Webb04, Maki02, Kneidinger01] and reviewed in [Rocchetta99]).

α-D-rhamnose is the nucleotide-activated donor of D-rhamnose units to the A-band lipopolysaccharide in Pseudomonas aeruginosa. This gram-negative organism synthesizes two variants of lipopolysaccharide, designated A-band and B-band. The O-antigen of the A-band lipopolysaccharide is a homopolymer of D-rhamnose residues arranged in repeating trisaccharide units, whereas the O-antigen of the B-band is a heteropolymer containing many different monosaccharides. Pseudomonas aeruginosa TAU-5 is a pathogen that causes opportunistic infections in animals and plants, and the lipopolysaccharide of the outer membrane contributes to its virulence. In [Webb04], in [Maki02], and reviewed in [Rocchetta99]). The biosynthesis of O-antigen in Escherichia coli is shown in MetaCyc pathway O-antigen building blocks biosynthesis (E. coli), although its composition is different from that of Pseudomonas aeruginosa TAU-5.

Aneurinibacillus thermoaerophilus L420-91 also has D-rhamnose residues on its surface. However, they are in the S-layer, a crystalline protein layer found on the outermost cell surface of many bacteria and archaea. The S-layer of this gram-positive, thermophilic bacterium is glycosylated with identical repeats of D-rhamnose and 3-acetamido-3,6-dideoxy-α-D-galactopyranose units (in [Kneidinger01]).

In this pathway, the final product is the D-rhamnose donor, GDP-D-rhamnose. It is synthesized from GDP-D-mannose in two steps, involving a dehydratase and a reductase. The precursor GDP-4-keto-6-deoxy-D-mannose is also a common intermediate for the synthesis of other GDP-monodeoxyhexoses such as: GDP-L-fucose, GDP-4-deoxy-D-talose, and GDP-deoxy-D-altrose; the GDP-dideoxyhexose GDP-colitose; and the GDP-dideoxy amino sugar GDP-D-perosamine (in [Webb04], in [Maki02], and in [Kneidinger01]). The biosynthesis of the starting substrate, GDP-D-mannose, is shown in the pathway link.
