Abstract

A bacteriophage growing on Escherichia coli K13, K20, and K23 strains carries a glycanase that catalyzes the hydrolytic cleavage of the beta-ketopyranosidic linkages of 3-deoxy-D-manno-2-octulosonic acid (KDO) in the respective capsular polysaccharides. The main cleavage product of the K23 polysaccharide has been identified by 1H- and 13C-n.m.r. spectroscopy as beta beta Ribfl----7 beta KDOp2----3-beta Ribfl----7KDO. Cleavage of polysaccharides containing alpha-pyranosidic, or 5-substituted beta-pyranosidic KDO is not catalyzed by the enzyme.
