<p> The so-called putative bacilysin exporter, bacE, part of the bacilysin biosynthesis operon, has been shown to be involved in self-protection to bacilysin [<cite idref="PUB00053614"/>] by permitting efflux of this antibiotic. </p> <p> The protein belongs to the Major Facilitator Superfamily (MFS), a class of single-polypeptide, general substrate carriers that transport small solutes in response to chemiosmotic ion gradients [<cite idref="PUB00007278"/>, <cite idref="PUB00007279"/>]. The primary structure of the protein is highly hydrophobic, suggesting the presence of 10-12 trans-membrane domains. </p> Bacilysin exporter BacE, putative
