The EROP-Moscow oligopeptide database [PDF]

open access: yesNucleic Acids Research, 2006
Natural oligopeptides may regulate nearly all vital processes. To date, the chemical structures of nearly 6000 oligopeptides have been identified from >1000 organisms representing all the biological kingdoms. We have compiled the known physical, chemical and biological properties of these oligopeptides--whether synthesized on ribosomes or by non ...
