1.B.14.1.8
The Ferripyochelin receptor, FptA (Michel et al., 2007). In addition to Fe3+, FptA takes up Co2+, Ga3+, and Ni2+ at low rates (Braud et al., 2009). The high resolution 3-d structure of FptA (2.0 Å) bound to iron-pyochelin has been solved (Cobessi et al. 2005). The pyochelin molecule provides atetra-dentate coordination of iron. The structure is typical of the TonB-dependent receptor/transporter superfamily.
