Plays a key role in regulating expression of enzymes involved in the catabolism of short chain fatty acids (SCFA) via both the glyoxylate (acetyl degradation route) and the methylcitrate cycle (propionate degradation route) (PubMed:22916289, PubMed:24705740). Required for intracellular growth in macrophages and for the assimilation of cholesterol-derived propionate (PubMed:22365605). PrpR acts as a transcriptional activator of prpDC and icl genes when propionate is the main carbon source, and as a ramB repressor (PubMed:22916289). During growth on propionate, PrpR also acts as a transcriptional repressor of dnaA, which encodes the DnaA initiator protein responsible for initiating chromosomal replication (PubMed:24705740). It is possibly involved in the regulation of genes responsible for controlling cholesterol utilization (PubMed:22365605).3 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence.
