Abstract:
:The surfaces of all microbes are 'sugar coated' with molecules such as lipopolysaccharides in Gram-negative bacteria, capsular polysaccharides in bacteria, lipoarabinomannans in mycobacteria and lipophosphoglycan in Leishmania. The basic structures of these glycoconjugates are known and, in the case of pathogens, they can function as virulence determinants. Recent publications have refined some of these structures and have elucidated interesting genes and proteins responsible for their biosynthesis.
