More active against E. coli and S. aureus at acidic pH 5.5. An incubation with 2.5 uM peptide reduced bacteria by 90%. Deletion of SAA1/2 in mice impaired the clearance of S. aureus in the skin. The bacterial killing of SAA at acidic pH was achieved via membrane binding and disruption ( Zheng et al., 2019 ).
