9.B.110 The DUF2339 (DUF2339) Family

The DUF2339 family consists of numerous proteins with 18 - 27-TMSs with possible repeats. Some of these proteins show significant sequence similarity to proteins annotated as ABC transporters, but they do not show similar topologies. Moreover, few show sequence similarity to ABC porters in TCDB.
