9.B.242.  The Uncharacterized Protein from Uncultured Bacteria-3 (UPUB3) Family 

Many proteins from uncultured bacteria comprise this family. There are no recognizable members from cultured bacteria.  These proteins may have a 4 TMS repeat, but this suggestion needs to be confirmed. These proteins show limited sequence similarity with glycosyl transferases of TC family 9.B.97.
