Biosynthesis of Streptococcal Cell Walls: A Rhamnose Polysaccharide

Protoplast membranes from Streptococcus pyogenes incorporated rhamnose into a preexisting polysaccharide when incubated with thymidine diphosphate rhamnose-C$^{14}$. This polysaccharide, when extracted from the membranes, did not give a precipitin reaction with group A antisera, but could be copreci...

More Information
Summary:Protoplast membranes from Streptococcus pyogenes incorporated rhamnose into a preexisting polysaccharide when incubated with thymidine diphosphate rhamnose-C$^{14}$. This polysaccharide, when extracted from the membranes, did not give a precipitin reaction with group A antisera, but could be coprecipitated with added group A polysaccharide by acetone. It is presumed to be a precursor to group specific polysaccharide of the streptococcal cell wall.
