Background. Theoretical and clinical developments suggest that opportunistic interventions could be developed that are more effective and satisfying to use than brief advice to quit smoking. Motivational consulting was influenced by the ‘stages of change’ model, self-efficacy theory, motivational interviewing, and the patient-centred clinical method. Aim. To compare the clinical and cost-effect...
متن کاملCharacterization of Amino Acid tRNA Ligases using the Analytical Ultracentrifuge
Quaternary structures of amino acid tRNA ligases/synthetases (aaRS) in the native as well as in denatured forms were examined by molecular weight determinations (paper I-IV). Analytical ultracentrifugation, gel electrophoresis, gel chromatography were used in these investigations. The aaRSs were obtained from bacteria and yeast: LysRS and ValRS from S. cerevisiae, AspRS, LysRS and SerRS from E....
متن کامل[Novel L-amino acid ligases catalyzing oligopeptide synthesis].
L-Amino acid ligase (EC 6.3.2.28) is a microbial enzyme catalyzing formation of an alpha-peptide bond from unprotected L-amino acids in an ATP-dependent manner. The YwfE protein from Bacillus subtilis 168 was the first reported L-amino acid ligase, and it synthesizes various dipeptides. Thereafter, several L-amino acid ligases were newly obtained by in silico analysis using the ATP-grasp motif....
متن کاملMechanism of action of amino acid transfer ribonucleic acid ligases.
The first reaction in protein biosynthesis has been presumed to be the interaction of ATP, amino acid, and enzyme (amino acid-activating enzyme, aminoacyl transfer RNA ligase, tRNA synthetase) to form an enzyme-bound aminoacyl adenylic anhydride. Such aminoacyl anhydrides could react forward with hydroxylamine or with tRNA or backward with [““PI-PPi. Experiments, primarily involving inhibitors,...

Members of the solute carrier (SLC) family of transporters are responsible for the cellular influx of a broad range of endogenous compounds and xenobiotics in multiple tissues. Many of these transporters are highly expressed in the gastrointestinal tract, liver, and kidney and are considered to be of particular importance in governing drug absorption, elimination, and cellular sensitivity of sp...
