GROUP A STREPTOCOCCUS CrgE PROTEIN

摘要

The invention provides methods of screening utilising the CrgE protein and the Streptococcus pyogenes bacterium expressing crgE. The invention also provides bacteria where the crgR and/or the crgE gene has been knocked out. The invention also provides fusion proteins comprising the polypeptide encoded by Spy1542 (crgE) and pharmaceutical compositions comprising CrgE.
