From: The cell envelope subtilisin-like proteinase is a virulence determinant for Streptococcus suis
Alignment of the catalytic triad (Asp 200 - His 239 - Ser 568 ; indicated by arrows) of S. suis SSU057 and homologous streptococcal subtilisin-like proteinases. Each catalytic triad is identified by UniProtKB accession numbers: A4VUI8 + A4VUI9 correspond to S. suis 05ZYH33 (SSU05-0811 + SSU05-0812); A4WOT0 + A4WOT1 correspond to S. suis 98HAH33 (SSU98-0811 + SSU98-0812); Q9F8Q4 corresponds to S. thermophilus PrtS; Q3JYS0 corresponds to S. agalactiae CspA; A3CQ08 corresponds to S. sanguinis PrtS; Q9A180 corresponds to S. pyogenes PrtS; Q3HV58 corresponds to S. pyogenes ScpC; P15926 corresponds to S. pyogenes ScpA; Q3K0M1 corresponds to S. agalactiae ScpB; Q04LP0 corresponds to S. pneumoniae PrtA.
