Histone H1 kills MRSA
Marsman et al. detect histone H1 in MRSA in human abscesses and demonstrate that it kills MRSA under physiological conditions. They identify through selective evolution and a genome-wide screen that histone H1 targets wall teichoic acids and permeabilizes potentiated membranes of metabolically active and dividing cells, providing molecular insight into host-mediated clearance of MRSA.
