CCA tRNA nucleotidyltransferase (, ''CCA-adding enzyme'', ''tRNA adenylyltransferase'', ''tRNA CCA-pyrophosphorylase'', ''tRNA-nucleotidyltransferase'', ''transfer-RNA nucleotidyltransferase'', ''transfer ribonucleic acid nucleotidyl transferase'', ''CTP(ATP):tRNA nucleotidyltransferase'', ''transfer ribonucleate adenylyltransferase'', ''transfer ribonucleate adenyltransferase'', ''transfer RNA adenylyltransferase'', ''transfer ribonucleate nucleotidyltransferase'', ''ATP (CTP):tRNA nucleotidyltransferase'', ''ribonucleic cytidylic cytidylic adenylic pyrophosphorylase'', ''transfer ribonucleic adenylyl (cytidylyl) transferase'', ''transfer ribonucleic-terminal trinucleotide nucleotidyltransferase'', ''transfer ribonucleate cytidylyltransferase'', ''ribonucleic cytidylyltransferase'', ''-C-C-A pyrophosphorylase'', ''ATP(CTP)-tRNA nucleotidyltransferase'', ''tRNA adenylyl(cytidylyl)transferase'', ''CTP:tRNA cytidylyltransferase'') is an enzyme with system name ''CTP,CTP,ATP:tRNA cytidylyl,cytidylyl,adenylyltransferase''. This enzyme catalyses the following chemical reaction : a tRNA precursor + 2 CTP + ATP a tRNA with a 3' CCA end + 3 diphosphate (overall reaction) :(1a) a tRNA precursor + CTP a tRNA with a 3' cytidine end + diphosphate :(1b) a tRNA with a 3' cytidine + CTP a tRNA with a 3' CC end + diphosphate :(1c) a tRNA with a 3' CC end + ATP a tRNA with a 3' CCA end + diphosphate The acylation of all tRNAs with an amino acid occurs at the terminal ribose of a 3' CCA sequence. == References == 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「CCA tRNA nucleotidyltransferase」の詳細全文を読む スポンサード リンク
