Gaomei Zhao,Changsheng Jia,Cheng Zhu,Minchao Fang,Chenwen Li,Yin Chen,Yingjuan He,Songling Han,Yongwu He,Jin-Sheng Gao,Tao Wang,Cheng Wang,Junping Wang +12 more
TL;DR: In this paper , the authors truncated the human defensin (HD) 5 structure by extracting the highly conserved γ-core motif and replaced the Glu and Ser residues with Arg residues to create the derivative RC18, which exhibited stronger potency than HD5, particularly against methicillin-resistant S. aureus (MRSA).
