9.B.255. The Uncharacterized Protein from Unculturable Bacteria-7 (UPUB7) Family These proteins are only from uncultureable bacteria. They have variable sizes (200 - 360 aas) and numbers of TMSs (4 - 8). It is possible, but not demonstrated, that these proteins are distantly related to the DMT superfamily (TC# 2.A.7).
Examples:
TC#	Name	Organismal Type	Example
9.B.255.1.1	Uncharacterized protein of 255 aas and 7 or 8 TMSs in a 5 or 6 (N-terminal) + 2 (C-terminal) arrangement.		UP of Candidatus Wolfebacteria bacterium

9.B.255.1.2	Uncharacterized protein of 353 aas and 7 or 8 TMSs in a 4 + 1 +2 or 3 arrangement.		UP of Candidatus Liptonbacteria bacterium

9.B.255.1.3	Uncharacterized protein of 336 aas and 5 or 6 TMSs in a 4 + 1 or 2 arrangement.		UP of the Parcubacteria group

9.B.255.1.4	Uncharacterized protein of 287 aas and 8 TMSs in a 4 + 2 + 2 arrangement.		UP of Candidatus Harrisonbacteria bacterium

9.B.255.1.5	Uncharacterized protein of 331 aas and 7 TMSs in a 4 + 1 + 2 arrangement.		UP of Candidatus Moranbacteria bacterium
