oa Editorial

This issue of Protein & Peptide Letters includes 13 papers contributed by members of the Editorial Advisory Board (EAB) of the journal. These individuals play an important role in reviewing submissions to the journal and in promoting PPL to their colleagues around the world. One of the 12 issues each year features papers from their laboratories. This issue deals with manuscripts that were submitted during 2011, but with peer review and revisions, the accepted papers are only being published now. We will work to improve the speed of the process in future EAB member issues. First, Ajoy Basak's laboratory has presented a paper titled “Proprotein Convertase Subtilisin Kexin9 (PCSK9): A Novel Target For Cholesterol Regulation”. This is a member of the mammalian subtilase family and is involved in degradation of the low density lipoprotein receptor. This work is important in the potential development of a new target for cholesterol lowering drugs. The second paper is from the laboratory of David Phoenix titled “Effect of Amidation on the Antimicrobial Peptide Aurein 2.5 from Australian Southern Bell Frogs”. In addition to demonstrating a 2.5-fold enhancement of activity against Klebsiella pneumonia by the C-terminally amidated peptide, this paper explores the surface properties, helical content, and monolayers using Langmuir techniques.....
