Nitrilases are involved in natural product biosynthesis and post translational modifications in plants, animals, fungi and certain prokaryotes. Nitrilases can also be used as catalysts in preparative organic chemistry. Among others, nitrilases have been used for the resolution of racemic mixtures. Nitrilase should not be confused with nitrile hydratase (nitrile hydro-lyase; ) which hydrolyses nitriles to amides. Nitrile hydratases are almost invariably co-expressed with an amidase, which converts the amide to the carboxylic acid, consequently it can sometimes be difficult to distinguish nitrilase activity from nitrile hydratase plus amidase activity. Nitrilase is a polypeptide consisting of alpha helices and beta sheets. It is 262 residues in length and its structure was determined through x-ray diffraction. The structure of nitrilase shown has a resolution of 1.57 Å or 0.157 nm. Nitrilase is an enzyme and therefore requires a ligand in order for it to become active. Magnesium ion is the ligand that is a tightly bound to the enzyme to allow for this activation.〔(Protein Data Bank )〕 Nitrilases are naturally found in some foods, notably barley. == 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「Nitrilase」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
