چکیده

The sedimentation coefficient of streptolysin O as determined by sucrose density gradient ultracentrifugation is 3.7S. An approximate molecular weight of 60,500 was calculated from the sedimentation velocity, and a similar value was obtained by Sephadex gel filtration. There was no measurable difference in the sedimentation coefficient of streptolysin O in either the active or reversibly inactive forms, indicating that there were at most only minor conformational differences between the two forms.

Isolation and identification of two hemolytic forms of streptolysin-O.

Streptolysin-O was isolated from culture supernatants of group-A beta-hemolytic streptococci (Richards strain) by ammonium sulfate and polyethylene glycol precipitation, DEAE-ion exchange chromatography, preparative isoelectric focusing, and chromatography on Sephacryl S-300. Two forms of the toxin possessing similar hemolytic capacity were identified. The native toxin was a single polypeptide ...

The Molecular Weight of Yeast Pl Double-stranded RNA*

The molecular weight of the double-stranded RNA (Pl dsRNA) always associated with the virus-like particles that occur in the yeast Saccharomyces cerevisiae was determined to be 3.5 + 0.1 X lo6 by equilibrium sedimentation. Methylmercuric-agarose gel electrophoresis yielded a value of 1.67 + 0.11 x lo6 for the single-stranded form. The sedimentation coefficient, 0 SZO+,, was determined by bounda...

Function of pH

1. The sedimentation coefficients of rabbit immunoglobulin G, four types of Fc fragments, univalent Fab and bivalent F(ab)2 fragments were measured as a function of pH. 2. In conjunction with molecular-weight determinations by sedimentation equilibrium, and with the behaviour on gel filtration, this enabled the state of association of the Fc fragments to be followed. 3. The type possessing an i...

Properties and subunit composition of the pig heart 2-oxoglutarate dehydrogenase.

The 2-oxoglutarate dehydrogenase, one of the component enzymes of the 2-oxoglutarate dehydrogenase complex, has been highly purified. The enzyme has a sedimentation coefficient (s&~) of 10.3 S and diffusion coefficient (&o,~) of 3.92 X lo-’ cm2 s-l. The weight average molecular weight was estimated to be about 216,000 from the sedimentation equilibrium data. The content of right-handed LY helix...
