High affinity (Km 16 mμM) pyruvate:H+ symporter, BtsT (from "Brenztraubensaure", the German word for pyruvate), formerly YjiY of 716 aas and 16 - 18 TMSs (Kristoficova et al. 2017). Regulated by Crp as well as the LytS-like histidine sensor kinase, BtsS (YehU) which senses extracellular pyruvate, and the corresponding LytTR-like response regulator, BtsR (YehT). Although the true inducer is extracellular pyruvate as noted above, it is induced by peptides as cells enter the stationary growth phase, presumably because pyruvate is released from these peptides (Kraxenberger et al. 2012). BtsT forms a complex with the MFS transporter, YhjX (TC# 2.A.1.11.3) and two sensor kinase/response regulator pairs, YehU/YehT and YdpA/YdpB (Behr et al. 2014). Both transporters are also posttranscriptionally regulated by CsrA (Behr et al. 2014).
