Halocins are bacteriocin-like proteins or peptides produced by many species of the family Halobacteriaceae. Halocin C8, excreted by the Halobacterium strain AS7092, is a single 6.3-kDa polypeptide with an isoelectric point of 4.4, which is sensitive to proteinase K but not to trypsin. Halocin C8 is quite stable, as it can be desalted, boiled, frozen, subjected to organic solvents, and stored in culture supernatant at 4°C or in dH2O at −20°C for more than 1 year without losing activity.
