The project aim was to describe proteomic changes in E. coli MG1655 strain after removal of oriC. Temperature-sensitive transcriptional repressor cI857 and its target promoter was used to control the expression of a serine recombinase from bacteriophage phiC31 (phiC31 integrase). cI857 is a temperat...

The stringent response inhibits DNA replication initiation in E. coli by modulating supercoiling of oriC
Initiation of DNA replication requires binding of the initiator protein, DnaA, to specific binding sites in the chromosomal origin of replication, oriC. In low G+C Gram-positive bacteria, the primosomal proteins DnaD and DnaB, in conjunction with loader ATPase DnaI, load the replicative helicase at ...

The stringent response enables bacteria to respond to a variety of environmental stresses, especially various forms of nutrient limitation. During the stringent response the cell produces large quantities of the nucleotide alarmone ppGpp, which modulates many aspects of cell physiology, including re...

Comparison of transcriptions in wild_type, delta-6 (deletion of six DnaA-box clusters (DBCs)), delta-5 and delta-DBC[yydA-yycS] strains, to see effect of the DBCs on transcription of neighboring genes and DnaA-regulated genes.
