The serotype-specific glucose side chain of rhamnose-glucose polysaccharides is essential for adsorption of bacteriophage M102 to Streptococcus mutans.

abstract：:Type IV secretion systems are employed by a wide variety of Gram-negative microorganisms for the translocation of macromolecules across the cell envelope. The translocated substrates (proteins, protein-DNA complexes and DNA) are as diverse as the organisms on the donor and recipient side of the translocation process. ...
