Streptococcus pyogenes, an important pathogen in humans, secretes an IgG specific endopeptidase named IdeS. To elucidate the mechanism that is responsible for this specificity, we have here characterized the activity of IdeS in detail. Both gamma chains of human IgG

Pathogenic bacteria have developed complex and diverse virulence mechanisms that weaken or disable the host immune defense system. IdeS (IgG-degrading enzyme of Streptococcus pyogenes) is a secreted cysteine endopeptidase from the human pathogen S. pyogenes with an extraordinarily high degree

Group A Streptococcus has evolved numerous mechanisms to evade the host immune system to survive, disseminate, and cause disease. Recently a secreted protein named Mac-1 was identified and shown to enhance survival of the pathogen. A new variant of Mac-1

A comparative in vitro survey of physiologically relevant human and microbial proteinases defined a number of enzymes that induced specific hinge domain cleavage in human IgG1. Several of these proteinases have been associated with tumor growth, inflammation, and infection. A
