3.A.1.33.2
Possible cobalt ion transporter of three subunits, Q8TSC7 (S-subunit, DUF1616, with 550 aas and 8 probable TMSs in a 1 (N-terminus) + 7 (C-terminus) arrangement), Q8TSC8 (A-subunit, ATPase, with 641 aas) and Q8TSC9 (T-subunit, 297 aas, probably with 6 or 7 TMSs). The protein with UniProt acc. # Q8TSC6, encoded adjacent to the three genes encoding the transporter, is CobN, a Co2+/Mg2+ celatase of 1302 aas, and adjacent thereto is a gene encoding a PQQ enzyme of 570 aas with 1 N-terminal TMS.
