Abstract

Streptococcus pyogenes has been shown to produce an extracellular cysteine protease which degrades gelatin, fibronectin, collagen, and other extracellular matrix (ECM) proteins. Degradation of the ECM allows bacteria to more easily invade tissues, which may lead to increased virulence. The production of gelatin-degrading enzymes was examined in Escherichia coli and Streptococcus pyogenes using zymography. By incorporation of gelatin into polyacrylamide gels, zymograms can determine the presence of active enzymes that degrade gelatin. This information may be useful in exploring the role of gelatinases in bacterial pathogenicity.

Determination of Bacterial Gelatinase Production By Zymography

Streptococcus pyogenes has been shown to produce an extracellular cysteine protease which degrades gelatin, fibronectin, collagen, and other extracellular matrix (ECM) proteins. Degradation of the ECM allows bacteria to more easily invade tissues, which may lead to increased virulence. The production of gelatin-degrading enzymes was examined in Escherichia coli and Streptococcus pyogenes using zymography. By incorporation of gelatin into polyacrylamide gels, zymograms can determine the presence of active enzymes that degrade gelatin. This information may be useful in exploring the role of gelatinases in bacterial pathogenicity.
