Published in Drug Week, June 25th, 2004
According to a study from the United States, "Sequences of 221 alpha-helical antimicrobial peptides (alphaAMPs) were compared and 63-166 of them were selected and analyzed using Perl programs. The results showed that aliphatic amino acids Gly, Leu, Ala, Ile, and two positively charged amino acids Lys and Arg were composed of more than 63% of the first 20 residues of alphaAMPs. The weighed mean membrane partitioning energies at positions from 1 to 25 of alphaAMPs were calculated."
"Profile of the partitioning energies suggests oblique membrane insertion and...
