title: Highly specific bacteriophage-associated polysaccharide hydrolases for Klebsiella aerogenes type 8.
abstract: Two phage-bound polysaccharide hydrolases specific for Klebsiella aerogenes type 8 exopolysaccharides were isolated. Each enzyme was specific for the polysaccharide produced by the host strain. One enzyme hydrolysed a pyruvylated and acetylated polymer, while the other only acted on the substrate lacking these substituents. Both enzymes were endogalactosidases releasing tetrasaccharides from their substrates which were only hydrolysed to a limited extent.
