9.B.304.1.1









Uncharacterized protein of 459 aas and 12 TMSs in a 4 + 4 + 4 arrangement.

Archaea
Candidatus Lokiarchaeota
UP of Lokiarchaeum sp. GC14_75
9.B.304.1.2









Uncharacterized protein of 90 aas and 2 TMSs.

Bacteria
Planctomycetota
UP of Gimesia maris
9.B.304.1.3









Uncharacterized protein of 101 aas and 2 TMSs.

Bacteria
Pseudomonadota
UP of Phenylobacterium sp. Root700
9.B.304.1.4









Histidine sensor kinase of 514 aas and 8 TMSs with 4 TMSs at the N-terminus and 4 TMSs at the C-terminus.  The central hydrophilic domain is the sensor kinase, and the C-terminal consists of two 2TMS domains in close proximity to each other.  The N-terminal 4 TMSs do not appear to belong to the 2TMS family.

Uncharacterized protein of 163 aas and 4 TMSs in a 2 + 2 TMS arrangement.

Bacteria
Pseudomonadota
UP of Methyloceanibacter marginalis
9.B.304.1.8









Histidine sensor kinase of 440 aas with 6 TMSs, 4 N-terminal (residues 1 - 140) and 2 C-terminal (residues 370 - 420). The last two TMSs are homologous to 2 of the 4 C-terminal TMSs in 9.B.304.1.4.
