2.A.76.1.3
Probable amino acid exporter, YahN or YhaM, of 233 aas and 6 TMSs.  Expression is under the control of the leucine-responsive protein, Lrp, and amino acids in the medium (Kutukova et al. 2005). The yahOM operon is induced by cysteine where the cysteine sensor is the DecR/YbaO protein, and this operon is involved in L-cysteine detoxification (Shimada et al. 2016).
