9.B.405. The 7 TMS Uncharacterized Ubiquitous Protein-1 (UUP1) Family The proteins of this family are of about 240 aas and have 7 TMSs. They occur in archaea, bacteria and eukaryotes. Members of the family have been annotated in the NCBI protein database as phytol kinases and phosphatidate cytidylyltransferases.
Examples:

9.B.405.2.1	Uncharacterized protein of 8 TMSs in an apparent 1 + 4 + 3 TMS arrangement. Possibly it has a 4 TMS repeatsss and then would have a 1 + 3 + 1 + 3 TMS arrangement.		UP of Chloroflexi bacterium (marine sediment metagenome)

9.B.405.2.2	Phosphatidate cytidylyltransferase of 233 aas and 7 TMSs in a 1 + 1 + 2 + 3 TMS arrangement.		PCT of Calothrix parasitica

9.B.405.2.3	Cytidylyltransferase family protein of 227 aas and 5 or 6 TMSs in a 1 or 2 + 2 + 2 TMS arrangement.		CT protein of Spirochaetes bacterium ADurb.Bin110 (anaerobic digester metagenome)

Examples:
