9.B.263.  The DUF2232 (DUF2232) Family 

These proteins are of about 320 aas and have 8 TMSs in an apparent 4 + 4 arrangement. Some of the homologs are designated YybS in the NCBI database.


Examples:

TC#NameOrganismal TypeExample
9.B.263.1.1

DUF2232 domain-containing proteinof 317 aas and 8 - 10 TMSs.

DUF2232 protein of Roseomonas stagni

 
9.B.263.1.2

DUF2232 protein of 325 aas and 8 TMSs

DUF2232 protein of Bradyrhizobium japonicum

 
9.B.263.1.3

DUF2232 domain-containing protein of 328 aas and 6 - 8 TMSs.  The TMSs show a 3 + 3 topology where in both sets of 3, the central TMS is broad and could be two TMSs, giving rise to an 8 TMS protein. This protein interlinks TC subfamilies 9.B.263.1 and 9.B.263.2.
