3.A.3.32.1
Functionally uncharacterized P-type ATPase family 32 (FUPA32) (multiple proteins from α-, β-, γ-, δ- and ε-proteobacteria (690-720 aas) (Chan et al. 2010).  The proteins in subfamily 3.A.3.32 may all be ferric iron uptake transporters as indicated by the characterized bacterial iron transport protein, FezB, included in TCDB under TC# 9.A.83.1.1 because it is reported to function with FezA, a 131 aa protein with a single N-terminal TMS.  This protein may prove to be an auxilliary protein for the FezB ATPase (see TC# 9.A.83.1.1) (Pi et al. 2023). Other FezAB systems have been characterized in Gram-negative bacterial (Pi et al. 2023).
