Words similar to oxyr
Example sentences for: oxyr
How can you use “oxyr” in a sentence? Here are some example sentences to help you improve your vocabulary:
Disulfide bond formation is associated with a conformational change that alters OxyR binding to DNA and allows the protein to activate the transcription of genes encoding enzymes, such as catalase and the alkylhydroperoxide reductase, that destroy H 2 O 2 . Once the H 2 O 2 concentration is decreased, OxyR is reduced and the system is reset.
Thus, the RsrA regulatory circuit provides another example, comparable to OxyR, in which the modification of a regulatory protein thiol group can be linked to a change in the transcriptional output of genes that remediate stress.
OxyR contains two critical cysteines that are oxidized to form an intramolecular disulfide bond when cells encounter peroxide stress (Zheng et al.
The unusually reactive cysteine in OxyR that is oxidized by H 2 O 2 to form the sulfenic acid intermediate can clearly be nitrosylated and glutathionylated in vitro (Hausladen et al.
The first of these examples is the OxyR transcription factor, which upregulates peroxide defenses in
