Abstract
The receptor for phage M-1 was present in the exopolysaccharide (EPS) of Rhizobium japonicum D211. The EPS was a heteropolysaccharide consisting of glucose, galactose, glucuronic acid, and glucosamine units. These monosaccharides prevented phage–cell attachment indicating that they may mimick the receptor. Phage–cell attachment was either stimulated or inhibited by Mg2+ and Ca2+ depending upon their concentration.An enzyme which depolymerized the exopolysaccharide releasing oligosaccharides was detected in the phage-infected cell lysates. A comparison of the properties of adsorption and those of the depolymerase enzyme indicated that the latter was a component of the phage and appeared to be involved in the phage–receptor interaction.
