9.B.404. The Uncharacterized Archaeal/Bacterial 8 TMS Protein-15 (UABP15) Family These proteins are generally of abou 300 - 340 aas in length and have 8 TMSs in an apparent 3 + 2 + 3 TMS arrangement.
Examples:
TC#	Name	Organismal Type	Example
9.B.404.1.1	Uncharacterized protein of 314 aas and 8 TMSs in a 3 + 2 + 3 TMS arrangement.		UP of Candidatus Prometheoarchaeum syntrophicum

9.B.404.1.2	Uncharacterized protein of 279 aas and 8 TMSs		UP of Methanobacteriaceae archaeon (subsurface metagenome)

9.B.404.1.3	Uncharacterized protein of 266 aas and 8 TMSs in a 1 + 3 + 1 + 3 TMS arrangement. This protein belongs to this family, but also shows appreciable sequence similarity to a member of the DMT superfamily (TC# 2.A.7.43.3; e-7 without filters, e-5 with filters) suggesting that this family may be a member of the DMT superfamily.		UP of Dethiobacter alkaliphilus

9.B.404.1.4	Uncharacterized protein of 296 aas and 8 TMSs.		UP of Antarcticibacterium flavum

9.B.404.1.5	Uncharacterized protein of 274 aas and 8 TMSs.		UP of Chloroflexi bacterium (bioreactor metagenome)

9.B.404.1.6	Uncharacterized protein of 290 aas and 8 TMSs in a 1 + 3 + 1 + 3 TMS arrangement.		UP of Petroclostridium xylanilyticum
