9.B.363. The Divergen PAP2 (PAP2) Family

These bacterial proteins are either small 4 TMS proteins with PFam # PF02681 and clan CL0525 (subfamily 1) or much larger with a 7 or 14 TMS topology in a 3 + 4 or 3 + 4 + 3 + 4 TMS arrangement (subfamily 2). In this last subfamily, the first and second 7 TMSs in the larger proteins probably represent repeat sequences. TMSs 1 - 4 in the protein with TC# 9.B.363.1.3 are homologous to TMSs 2 - 5 in the protein with TC# 9.B.363.2.1.
