title: Isolation of two endo-beta-N-acetylglucosaminidases with different specificities from Pseudomonas sp.
abstract: Two endo-beta-N-acetylglucosaminidases (PI and PII) have been isolated from the culture fluid of Pseudomonas sp. The substrate specificity of the PI enzyme was very similar to that of Endo-H from Streptomyces plicatus. On the contrary, the PII enzyme had a novel substrate specificity that degraded both high-mannose type and hybrid type oligosaccharides derived from ovalbumin, and the core structure of complex type oligosaccharides derived from human transferrin and porcine pancreatic lipase.
