Antimicrobial characterization of human β-defensin 3 derivatives

DM Hoover, Z Wu, K Tucker, W Lu… - Antimicrobial agents …, 2003 - Am Soc Microbiol
ABSTRACT Human β-defensin 3 (hBD3) is a highly basic 45-amino-acid protein that acts
both as an antimicrobial agent and as a chemoattractant molecule. Although the nature of its …

Identification of structural traits that increase the antimicrobial activity of a chimeric peptide of human β-defensins 2 and 3

B Spudy, FD Sönnichsen, GH Waetzig… - Biochemical and …, 2012 - Elsevier
Antimicrobial peptides participate in the first line of defence of many organisms against
