Adding amino acids to the genetic repertoire.
Considerable progress has been made in expanding the number and nature of genetically encoded amino acids in Escherichia coli, yeast and mammalian cells in the past four years. To date, over 30 unnatural amino acids have been cotranslationally incorporated into proteins with high fidelity and efficiency by means of a unique codon and corresponding orthogonal tRNA-aminoacyl-tRNA synthetase pair....
متن کاملPerformance of 2-Amino Tetraphenyl Porphyrin as Stationary Phase in RP-HPLC of Amino Acids
The search for new stationary phases has been one of the predominant concerns in high performance liquid chromatography (HPLC) in order to achieve better resolutions, longer column lives, and reduce the time of analysis. A chromatographic packing for separation of underivatized amino acids (AAs) were prepared by dynamically coating 2-amino tetraphenyl prophyrin (atpp) on a C-18 reversed-pha...
متن کاملInfluence of vegetable amino acids and oils supplementation of on Chlorella vulgaris amino acid profile
The aim of the present research is to investigate the profile of amino acid of Chlorella vulgaris supplemented with some plant amino acid and oil extracts. The bioactive oil and amino acid from four Iranian medicinal plants, namely Oliveria decumbens, Thymus kotschyanus, Trachyspermum ammi, and Zataria multiflora were obtained. The LC-MS / MS analysis demonstrated that the major amino acids com...
متن کاملProteins and Amino Acids
Proteins, from the Greek proteios, meaning first, are a class of organic compounds which are present in and vital to every living cell. In the form of skin, hair, callus, cartilage, muscles, tendons and ligaments, proteins hold together, protect, and provide structure to the body of a multi-celled organism. In the form of enzymes, hormones, antibodies, and globulins, they catalyze, regulate, an...
