Abstract: | "Putative a-factor peptides YIIKGVFWADP, YIIKGVFWANP, YIIKGLFWADP, YIIKGLFWANP, YIIKGVFWDPA, and YIIKGVFWDPACVIA and several peptide derivatives were synthesized and were found to be inactive in growth arrest assays, yet they blocked the activity of biological a-factor. Antagonism was greatest with YIIKGVFWDPAC(palmitoyl)VIA. Thus, the structure of a-factor may be a lipopeptide resembling this palmitoylated pentadecapeptide" |
