3.A.1.14.28
Iron-siderophore (staphylobactin, made by S. aureus) uptake system, SirABCD (A = periplasmic receptor (R); B and C = membrane proteins with 9 or 10 TMSs (M), and D (IsdC) is likely to be the periplasmic auxiliary protein with 2 TMSs, N- and C-terminal (Dale et al. 2004). This last protein is also given the TC# 9.A.39.1.2 as a member of its own family. The ATPase subunit is not known, but it could be the protein with genbank acc# WP_001080807.1.
