GOLDSTEIN, LEON, AND PAUL J. PALATT. Trimethylamine oxide excretion rates in elasmobranchs. Am. J. Physiol. 227(6) : 1268-1272. 1974.-The purpose of this study was to investigate the relationship between rates of excretion and rates of biosynthesis of trimethylamine oxide (TMAO) in elasmobranchs. TMAO excretion rates were estimated in four elasmobranchs previously shown to differ in their abili...
UNLABELLED Escherichia coli senses and responds to trimethylamine-N-oxide (TMAO) in the environment through the TorT-TorS-TorR signal transduction system. The periplasmic protein TorT binds TMAO and stimulates the hybrid kinase TorS to phosphorylate the response regulator TorR through a phosphorelay. Phosphorylated TorR, in turn, activates transcription of the torCAD operon, which encodes the p...
Microbial communities inhabiting the deep-sea salt-saturated anoxic lakes of the Eastern Mediterranean operate under harsh physical-chemical conditions that are incompatible with the lifestyle of common marine microorganisms. Here, we investigated a stable three-component microbial consortium obtained from the brine of the recently discovered deep-sea salt-saturated Lake Thetis. The trophic net...
High-quality GaAs/AlGaAs quantum well and modulation-doped heterostructures have been grown by low-pressure organometallic vapor phase epitaxy (OMVPE) using trimethylamine alane (TMAA) as a new aluminum source. TMAA is an alternative to the conventional organometallic precursors and offers the advantage of substantially reduced oxygen and carbon incorporation in AlGaAs. Intense photoluminescenc...
