In enzymology, a RNA-3'-phosphate cyclase () is an enzyme that catalyzes the chemical reaction :ATP + RNA 3'-terminal-phosphate AMP + diphosphate + RNA terminal-2',3'-cyclic-phosphate Thus, the two substrates of this enzyme are ATP and RNA 3'-terminal-phosphate, whereas its 3 products are AMP, diphosphate, and RNA terminal-2',3'-cyclic-phosphate. This enzyme belongs to the family of ligases, specifically those forming phosphoric-ester bonds. The systematic name of this enzyme class is RNA-3'-phosphate:RNA ligase (cyclizing, AMP-forming). This enzyme is also called RNA cyclase. ==Structural studies== As of 2010, three structures have been solved for this class of enzymes, with PDB accession codes and , (un-adenylated) and (adenylated). 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「RNA-3'-phosphate cyclase」の詳細全文を読む スポンサード リンク
