lldR coding sequence of <i>Salmonella</i> Typhimurium ATCC14028 which is part of the lactate inducer system. lldR is responsible for the induction of the lldRPD operon and encodes a putative regulatory protein (Gillis et al., 2019). Further, the lldR operon induces the lactate metabolism if lactate is the sole carbon source (). Part of the <a href="https://parts.igem.org/Part:BBa_K3861005">pKF01</a> backbone.

lldR

lldR coding sequence from Salmonella Typhimurium ATCC14028. LldR regulates the transcription of the lldPRD operon which is involved in lactate metabolism. LldR represses the expression of the the lldRPD operon genes by binding to two operator regions of PlldR promoter and forming a loop.1,2. The lldR gene will be constituvely expressed in our designed backbone pKF01 (BBa_K3861005), and will allow for tight regulation of genes under the lldR promoter (BBa_K1847008).
