A study of the phosphate linkages in phosphomannan in cell walls of Saccharomyces cerevisiae.


1. The phosphomannan of Saccharomyces cerevisiae was released by Pronase digestion of cell walls and isolated by chromatography on DEAE-cellulose or by precipitation with borate-Cetavlon solutions. Mannose and phosphorus were present in the molar ratio 18:1 and the phosphate groups were in the diester form. 2. Hydrolysis with acid gave mannose 6-phosphate… (More)
