Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Halocin-C8: Has antibacterial activity against a wide variety of haloarchaeons. Causes cell lysis and death, possibly by disrupting the cell wall (PubMed:12811620).1 Publication
Immunity protein HalI: Acts as an immunity protein for halocin-C8. Able to block the halocin-C8 activity by sequestering the activity of halocin-C8 through specific and direct binding (PubMed:15978083, PubMed:18658263).2 Publications

Miscellaneous

Halocin-C8: Is quite robust, as it can be desalted, boiled, subjected to organic solvents, and stored at 4 degrees Celsius for extended periods without losing activity.1 Publication

<p>The checksum is a form of redundancy check that is calculated from the sequence.
