Escherichia coli K-12 substr. MG1655 RNA: RydC small regulatory RNA



Gene: rydC Accession Numbers: G0-10592 (EcoCyc), b4597, ECK4407

Regulation Summary Diagram: ?

Regulation summary diagram for rydC

Summary:
RydC is a small RNA regulator of the expression of yejABEF, which encodes a predicted ABC permease [Antal05], and of the transcriptional regulator CsgD [Bordeau14].

Hfq binds to RydC in vivo [Zhang03b] and in vitro and stabilizes it [Antal05]. RydC folds into a pseudoknot structure [Zhang03b]; Hfq facilitates unfolding of the pseudoknot and thereby enhances the interaction of RydC with its mRNA target [Bordeau14]. The yejABEF mRNA was found to bind the RydC-Hfq complex [Zhang03b].

A rydC deletion strain has no detectable growth defect, but overexpression of RydC leads to a temperature-sensitive growth defect on minimal medium with glycerol, maltose, or ribose as the carbon source and leads to degradation of yejABEF mRNA [Antal05].
