For example, skin expression of the antimicrobial protein RNase 7 has an important role in the protection of human skin against E. faecium colonization [47].The function of mprF1 is not clear from our results or from the data presented by Roy and Ibba [9], [10]; there seems to be no obvious effect on the cell wall lipids, and the 12030ΔmprF1 mutant has been tested also by OPA, in the mouse sepsis and in the autolysis assay. Here, RNASE7 is linked to Sepsis.
