Characteristics of Streptolysin O Action [PDF]
Infection and Immunity, 1971 A study of the lysis of rabbit erythrocytes by streptolysin O (SO) revealed at least two steps in the hemolytic process. The initial interaction between SO and erythrocytes is the adsorption of the toxin molecule to the cell surface. Adsorption occurred at 4 C and was independent of ionic strength and p H; these ...

THE PURIFICATION AND PROPERTIES OF STREPTOLYSIN S [PDF]
Journal of Experimental Medicine, 1950 Considerable purification of streptolysin S has been achieved by fractionation of crude bacterial filtrates with methanol, under controlled conditions of pH, ionic strength, and temperature. The final material (P III) consisted of two electrophoretic components. The purified material was employed for kinetic studies, the results of which

Characteristics of streptolysin S hemolysis [PDF]
Infection and Immunity, 1976 The characteristics of hemolysis produced by streptolysin S (SLS) were investigated in rabbit erythrocytes. Treatment of erythrocytes with SLS at various temperatures prior to incubation at 37 C revealed an initial temperature-dependent interaction between toxin and the cells.

Reactivation of Streptolysin S by Oligonucleotide
Zeitschrift für Naturforschung C, 1987 Abstract Oligonucleotide-streptolysin S complex inactivated by alkali treatment remains nonhemolytic, even after acidification and mixing with intact carrier oligonucleotide rich in guanyl residue. Upon dehydration, how ever, the inactive streptolysin S-oligonucleotide mixture turned to be hemolytic, and this reactivation of the hem ...

Angewandte Chemie, Volume 138, Issue 13, 23 March 2026.A large variety of chemistry‐based ubiquitin probes have been developed. ABSTRACT Ubiquitin (Ub) and ubiquitin‐like proteins (Ubls) orchestrate diverse cellular processes through reversible post‐translational modification of target proteins. Their conjugation is governed by a cascade of E1 activating, E2 conjugating, and E3 ligating enzymes, while ...

Cellular location of streptolysin O [PDF]
Infection and Immunity, 1975 Streptolysin O was measured in subcellular fractions of group A streptococci obtained after preparation of protoplasts in a hypertonic buffer containing raffinose. Most of the activity was located in the periplasm (the region between cell wall and membrane) and did not differ in several characteristics from that of extracellular streptolysin O.

Esterase Activity of Streptolysin-O [PDF]
Journal of General Microbiology, 1972 SUMMARY: Purified streptolysin-O, from group-C streptococci, H46A, whose identity with NAD-glycohydrolase (EC.3.2.2.5) was reported earlier, has been shown to hydrolyse 4-nitrophenyl-esters. With 4-nitrophenylacetate as substrate, Km was 6.6 × 10~5 M; turnover number was 10000 mol substrate/mol enzyme/min and optimum pH was 7.8 to 8.5.
