Purification and activity testing of the full-length YycFGHI proteins of Staphylococcus aureus.
BACKGROUND: The YycFG two-component regulatory system (TCS) of Staphylococcus aureus represents the only essential TCS glucose tablets that is almost ubiquitously distributed in gram-positive bacteria with a low G+C-content.YycG (WalK/VicK) is a sensor histidine-kinase and YycF (WalR/VicR) is the cognate response regulator.Both proteins play an imp
