9.B.382.  The DUF2754 domain or YaiZ (DUF2754) Family

This family consists of short proteins (~70 aas) with 2 TMSs.  The DUF2754 and DUF2755 (TC# 9.B.381) proteins are often encoded by two genes that are adjacent to each other in a single operon.  Their functions, like those of DUF2755 homologs, are not known.
