9.B.239. The Uncharacterized Bacterial 10 - 13 TMS Protein (UBP2) Family This family consists of proteins that vary in size and topology (10 - 13 TMSs) and may be distantly related to the family with TC# 9.B.142, a family of glycosyl transferases, but this is not established. NCBI BLAST searches bring up many homologues in both cultered and uncultured bacteria. It contains no recognizable Pfam domains.
This family belongs to the Glycosyl/Acyl Transferase (GAT) Superfamily.
Examples:
TC#	Name	Organismal Type	Example
9.B.239.1.1	Uncharacterized protein of 451 aas and 10 - 12 TMSs.		UP of Candidatus Beckwithbacteria bacterium

9.B.239.1.2	Uncharacterized protein of 412 aas and 10 or 11 TMSs. May be related to glycosyl transferases in family with TC# 9.B.225.		UP of Candidatus Roizmanbacteria bacterium

9.B.239.1.3	Uncharacterized protein of 655 aas and 12 TMSs. Shows similarity with members of T family 9.B.142, a family of glycosyl transferases.		UP of Desulfovibrio ferrireducens

9.B.239.1.4	Uncharacterized protein of 307 aas and 10 TMSs. Shows similarity (e-7) to 9.B.142, a family of glycosyl transferases.		UP of Saprospira grandis
