D. Gerlach et al., PURIFICATION AND CHARACTERIZATION OF STREPTOLYSIN-O SECRETED BY STREPTOCOCCUS-EQUISIMILIS (GROUP-C), Infection and immunity, 61(6), 1993, pp. 2727-2731
Streptolysin O (SLO) was purified from culture supernatants of group C
streptococci. The final product was either the complete, native molec
ule (SLOn [pI, 6.0]) with the N-terminal sequence (Asp)-Ser-Asn-Lys-Gl
n-Asn-Thr-Ala-Asn-Thr-Glu-Thr- or a large fragment (SLOf [pI, 7.31) wi
th the N-terminal sequence -Glu-Met-Pro-Leu-Glu-Ser-Ala-Glu-Lys-Glu-Gl
u-Lys-.
