High sodium chloride concentrations inhibit staphylococcal enterotoxin C gene (sec) expression at the level of sec mRNA.

Expression of the staphylococcal enterotoxin type C gene (sec) is regulated in response to both high NaCl concentrations (osmolarity) and the accessory gene regulator (agr). agr is a global regulator that alters the expression of many genes in Staphylococcus aureus. In this report, we have demonstrated that osmoregulation of sec occurs at the level of mRNA independently of an intact agr allele....

Steady-state staphylococcal enterotoxin type C mRNA is affected by a product of the accessory gene regulator (agr) and by glucose.

The effects of the accessory gene regulator (agr) and glucose on staphylococcal enterotoxin type C (SEC) gene (sec+) expression were examined. For the agr studies, a Tn551 insertionally inactivated agr was transferred into two different sec+ Staphylococcus aureus strains. Western blot (immunoblot) analysis showed that each of the sec+ Agr- derivatives produced less extracellular SEC than their ...

SECRET AGENT and SPINDLY have overlapping roles in the development of Arabidopsis thaliana L. Heyn.

O-GlcNAc transferase (OGT) catalyses transfer of GlcNAc (N-acetylglucosamine) to serine or threonine of proteins. The Arabidopsis OGTs, SECRET AGENT (SEC) and SPINDLY (SPY) have overlapping functions during gametogenesis and embryogenesis. SPY functions in a number of processes including circadian, light, and gibberellin (GA) responses. The role of SEC in plant development and GA signalling was...

Changes in the PPla mRNA Level and PP1 Activity of Ascites Hepatomas at Different Cell Growth Rates

It is now well established that the type la of serine/threonine protein phosphatases (PP1α) may be implicated in malignant phenotype. Although the PP1α mRNA level increased in livers at preneo-plastic stages of hepatocarinogenesis and all of examined rat ascites hepatomas, unexpectedly, dra-matically decreased in some of primary hepatomas. In order to elucidate the low level of PP1α mRNA in som...

RNase III initiates rapid degradation of proU mRNA upon hypo-osmotic stress in Escherichia coli.

Hyper-osmotic stress strongly induces expression of the Escherichia coli proU operon encoding a high affinity uptake system for the osmoprotectants glycine betaine and proline betaine. Osmoregulation of proU takes place at the transcriptional level by upregulation of the promoter at high osmolarity and repression of transcription by the nucleoid-associated protein H-NS at low osmolarity. In the...
