Electrophoretic characteristics of staphylococcal hyaluronate lyase.
Partially purified staphylococcal hyaluronidase was studied with respect to its electrophoretic properties by the use of starch slurry or semisolid Noble agar as a matrix. The polarity of enzyme activity was found to be cathodal on starch and anodal on agar gel. The electrophoretic migration of the partially purified enzyme on starch, as a function of pH, suggested that the enzyme has an isoele...
متن کاملStaphylococcal hyaluronate lyase: purification and characterization studies.
Staphylococcal hyaluronate lyase (hyaluronidase) derived from a pathogenic strain of staphylococcus was purified by means of salt fractionation with ammonium sulfate and gel filtration through Sephadex G-100. Most of the enzyme activity from concentrated culture supernatant fluids of staphylococci was obtained in a fraction precipitated by 90 to 100% saturation with ammonium sulfate. A small am...
متن کاملAnalysis of a second bacteriophage hyaluronidase gene from Streptococcus pyogenes: evidence for a third hyaluronidase involved in extracellular enzymatic activity.
The hyaluronidase gene (hylP2) from a second group A streptococcal bacteriophage was isolated from ATCC T-type-22 hyaluronidase-producing strain 10403, a strain known to produce increased amounts of extracellular hyaluronidase. Sequence analysis of hylP2 and alignment with the previously described bacteriophage hyaluronidase gene (hylP) showed a high degree of similarity; however, hylP2 had del...
متن کاملGenotypic and Phenotypic Assessment of Hyaluronidase among Type Strains of a Select Group of Staphylococcal Species
Hyaluronidases degrade hyaluronic acid, a major polysaccharide of the extracellular matrix of tissues, and are considered important for virulence in a number of Gram-positive and -negative bacteria. The purpose of the present study was to determine the prevalence of hyaluronidase among clinical strains of Staphylococcus aureus and among other Staphylococcus species. Spent media and chromosomal ...
متن کاملStaphylococcal Sensitization: Specific Biological Effects of Phage K on the Bacterial Cell Wall in Lysis-from-without.
Ralston, Doris J. (University of California, Berkeley). Staphylococcal sensitization: specific biological effects of phage K on the bacterial cell wall in lysis-from-without. J. Bacteriol. 85:1185-1193. 1963.-Phage K, shown previously to sensitize staphylococcal-wall mucopeptide to the action of a phage-induced enzyme, virolysin, was found to act in a specific manner in that its sensitizing eff...
