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

Biochemistry, 43(49), 15540-15549 (2004-12-08)
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

Host innate immune responses to DNA viruses involve members of the nucleotide-binding domain, leucine-rich repeat and pyrin domain containing protein (NLRP) family, which form "inflammasomes" that activate caspase-1, resulting in proteolytic activation of cytokines interleukin (IL)-1β and IL-18. We hypothesized

We describe a fast and informative method to investigate the posttranslational modifications of monoclonal antibodies (MAbs). The MAb is first digested by a specific enzyme that cleaves heavy chains under the hinge domain. After reduction of disulfide bridges, three polypeptide

The immunoglobulin degrading enzyme of Streptococcus pyogenes, IdeS, is an unusual cysteine protease produced by group A streptococci for which the only known substrate is immunoglobulin G (IgG). To date, IdeS has not been found to cleave any of the
