  • regulon
  • In S. enterica , overexpression of oatA led to shorter lag times on sulfate-limiting medium and that these delayed lag times were due to increased expression of the cysteine regulon, as indicated by RT-qPCR results. (frontiersin.org)
  • serine
  • Through deletion of the l -cysteine desulfhydrases (CD) and overexpression of the native serine acetyltransferase (CysE), the initial l -cysteine-producing strain CYS-2 was constructed to produce 58.2 ± 5.1 mg/L of l -cysteine. (springer.com)
  • Carfagna S, Salbitani G, Vona V, Esposito S (2011) Changes in cysteine and O-acetyl-L-serine levels in the microalga Chlorella sorokiniana in response to the S-nutritional status. (springer.com)
  • In vitro studies with the cysJIH , cysK , and cysP promoters have confirmed that they are inefficient at forming transcription initiation complexes without CysB and N-acetyl-L-serine. (asmscience.org)
  • oxidative
  • To validate this transcriptome-phenotype association we grew L. lactis MG1363 in the absence of cysteine which led to enhanced robustness towards oxidative stress. (uva.nl)
  • respiratory
  • Although haloarchaea share certain features in order to adapt to their extreme environment, i.e. acidic protein machineries, respiratory chains and rhodopsins, their metabolism is considerably different from each other. (springer.com)
  • regulatory
  • We report the first crystal structure of the regulatory domain of an OxyR protein (NMB0173 from N. meningitidis ) in the reduced state i.e. with cysteines at positions 199 and 208. (biomedcentral.com)
  • expression
  • In summary, we present a dynamic bacterial RNA structurome and find that the expression of virulence-relevant functions in Y. pseudotuberculosis and reprogramming of its metabolism in response to temperature is associated with a restructuring of numerous mRNAs. (pnas.org)
