2.A.1.57.3
Iron-yersiniabactin (Ybt) transporter of 467 aas and 12 TMSs, YbtX (Bobrov et al. 2014). Yersiniabactin can also bind zinc ions with high affinity and feed the Zn2+ into this MFS transporter, YbtX (Bobrov et al. 2014). In fact, the siderophore, Ybt, is required for growth under Zn2+-deficient conditions in a strain lacking ZnuABC (see 3.A.1.15.5 for the E. coli ortholog).
