Project description:To identify CdbA binding sites on Myxococcus xanthus genome in vivo we performed ChIP-seq, using a polyclonal anti-FLAG antibody and a strain endogenously expressing CdbA_3xFLAG. A WT DK1622 strain was used a negative control and a strain endogenously expressing ParB_3xFLAG was used as positive control.
Project description:This study addresses the key role of the extracytoplasmic function (ECF) sigma factor DdvS in the Gram-negative bacterium Myxococcus xanthus. It allows us to determine its regulon and it shows that the expression of ddvS and its regulón depends on the global regulatory complex CarD-CarG.
Project description:In Myxococcus xanthus 55% of the more than 250 two-component signal transduction systems (TCS) genes are orphan. We hypothesized that the histidine kinase SgmT and the response regulator DigR, which comprises a DNA binding domain of the HTH_Xer type, function together to regulate gene expression. We performed genome-wide expression profiling experiments to determine wether the same set of genes are differentially expressed in the ΔdigR and ΔsgmT mutants.
