9.B.240. The Uncharacterized Prokaryotic 10 - 12 TMS Protein-1 (UPP1) Family
This family is only distantly related, if at all, to any other family currently (2018) in TCDB. It includes members from both culturable and unculturable bacteria and archaea. Some members show weak similarity with members of the ABC, OPT and P-type ATPase families (C-terminal domain).
