<p> This family consists of remarkably well-conserved proteins from gamma and beta Proteobacteria, heavily skewed towards organisms of marine environments. This family has an OsmC-like N-terminal domain. It shares a central domain, modeled by <db_xref db="INTERPRO" dbkey="IPR003776"/>, with other families of smaller proteins. The function is unknown. Fifteen of the first sixteen members of this family are from selenouridine-positive genomes, but this correlation may be fortuitous. </p> Conserved hypothetical protein CHP03549
