9.B.29.2.7









Uncharacterized protein of 212 aas and 5 TMSs (B8GHI5).  The adjacent gene encodes a homologue of 209 aas and 5 TMSs (B8GHI4; e-41), then a 415 aas protein with 2 TMSs, N- and C-terminal (B8GHI3),  then an ABC ATPase of 234 aas (B8GHI2), then a type 3 membrane ABC protein of 4 TMSs (B8GHI1) and then an inner membrane PrsW type protease (B8GHI0).  B8GHI2 and B8GHI1 appear to comprise an ABC transporter assigned TC# 3.A.1.122.21. This protein may be a chitinase (see also TC# 1.E. (Krone et al. 2023).

YknW, a membrane protein of 231 aas and 5 TMSs, is part of an unusual four-component ABC transporter, which is required for protection against the killing factor SdpC (sporulation-delaying protein). YknW plays an essential role in the assembly of the YknXYZ ABC transport complex (TC# 3.A.1.122.2) and interacts directly with it (Yamada et al. 2012).
