Abstract
The present invention provides novel kinocidin peptides comprising a C-terminal portion of a kinocidin, wherein the C-terminal portion encompasses an α-helical secondary structure and further displays antimicrobial activity. The kinocidin peptides of the invention are derived from and correspond to a C-terminal portion of a kinocidin that includes a γκo core and that can be a CXC, CC, or C class chemokine. Structural, physicochemical and functional properties of this novel class of antimicrobial peptides and amino acid sequences of particular kinocidin peptides are also disclosed. The invention also provides related antimicrobial methods.
Claims12
A method for treating an infectious disease or condition in a subject in need of such treatment comprising administering to the subject an effective amount of a peptide which (a) is 50 amino acid residues or less in length, (b) comprises a C-terminal portion α-helical amino acid sequence of a kinocidin and a γKC core motif of the formula:
- NH2[C]-[X10-13]-[GX2-3C]-[X2]-[P]COOH, (SEQ ID NO:39)
- wherein X represents any amino acid, and (c) has antimicrobial activity, wherein said kinocidin is a CXC, CX3C, CC, or C class chemokine and comprises a γKC core.
