3.A.1.122.19
ABC3-type efflux porter, YtrEF, encoded within an operon, ytrABCDEF, apparently encoding two ABC exporters, one, YtrBCD, with TC# 3.A.1.153.1, and the other, this one. The operon is induced in early stationary phase under the control of YtrA, a GntR-type HTH transcriptional regulator, probably a repressor (Yoshida et al. 2000). These authors suggest this operon may be involve in acetoin secretion and/or reutilization.
