2.A.79.2.1
YjjP (P0ADD5)/YjjB (P0ADD2) are of 256 aas and 5 TMSs; (DUF1212) and of 157 aas and 4 or 5 TMSs, respectively. yjjPB gene expression is regulated by HNS (a repressor) and LeuO (which antagonizes the repressive activity of HNS) (Stratmann et al. 2008). These proteins are encoded within a two gene operon, yjjPB, which encodes a two component dicarboxylate (succinate, fumarate and malate) transporter that has been shown to catalyze succinate efflux (Fukui et al. 2017). It is similar to the dicarboxylate/succinate transporter, YjjPB, of Enterobacter aerogenes (Fukui et al. 2018).
