In enzymology, an alanine-tRNA ligase () is an enzyme that catalyzes the chemical reaction :ATP + L-alanine + tRNAAla AMP + diphosphate + L-alanyl-tRNAAla The 3 substrates of this enzyme are ATP, L-alanine, and tRNA(Ala), whereas its 3 products are AMP, diphosphate, and L-alanyl-tRNA(Ala). This enzyme belongs to the family of ligases, to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds. The systematic name of this enzyme class is L-alanine:tRNAAla ligase (AMP-forming). Other names in common use include alanyl-tRNA synthetase, alanyl-transfer ribonucleate synthetase, alanyl-transfer RNA synthetase, alanyl-transfer ribonucleic acid synthetase, alanine-transfer RNA ligase, alanine transfer RNA synthetase, alanine tRNA synthetase, alanine translase, alanyl-transfer ribonucleate synthase, AlaRS, and Ala-tRNA synthetase. This enzyme participates in alanine and aspartate metabolism and aminoacyl-trna biosynthesis. ==See also== *Sticky mouse - mutation in the gene 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Alanine—tRNA ligase」の詳細全文を読む スポンサード リンク
