Strain Escherichia coli 042
Replicon chromosome
Sequence Protein sequence (279 a.a.); Nucleotide sequence (837 bp)
Description Methylation of GATC-32 caused a significant decrease of 267 affinity of Fur for the P4532 promoter and A Dam-methylated P4532 fragment was subjected to EMSA with the reconstituted σ70-RNAP complex shows σ70-RNAP binding was diminished on the methylated P4532 fragment.By contrast, the activity of the promoter fusion in the fur-dam strain increased ~ 16-fold compared to the wild-type strain,and ~1.4-fold compared to the fur mutant.
