WebMay 25, 1999 · OxyS RNA levels are elevated for approximately 20 min in wild-type cells (ref. 1, see also Fig. 2A). Because oxyS transcription is a downstream event of OxyR activation, we sought to establish a direct method of monitoring the kinetics of OxyR oxidation. This was achieved by alkylating the C199 and C208 thiol groups, present in reduced but not ... WebNov 17, 2024 · These genes belong to multiple pathways such as transport, metabolic process, proteolysis, and transcription; therefore, OxyS RNA seems to promote cephalothin resistance via multiple routes rather than a single pathway.

WebOct 15, 1998 · OxyS is a small untranslated RNA which is induced in response to oxidative stress in Escherichia coli. This novel RNA acts as a global regulator to activate or repress the expression of as many as 40 genes, including the fhlA‐encoded transcriptional activator and the rpoS‐encoded σs subunit of RNA polymerase. WebMay 17, 2002 · The Xist RNA is produced by the inactive X chromosome and spreads in cis along the chromosome ( 13 ). The chromosome-associated RNA has been proposed to recruit proteins that affect chromatin structure; however, much remains to be learned about the mechanism by which Xist and other long ncRNAs establish and/or maintain gene … WebThe OxyS RNA (oxidative stress RNA) of E. coli is 107–109 nt in length with two stem loops and without a start codon. It is induced to high levels after oxidative stress. The OxyS RNA regulates the expression of some 40 genes in E. coli by activation or repression and helps to protect the cells against oxidative stress ( Altuvia et al., 1997 ). latin name for lonely
