Abstract
(EN) [Problem] The present invention provides: a novel endo-β-N-acetylglucosaminidase (Endo-Om); and a gene for the endo-β-N-acetylglucosaminidase (Endo-Om). [Solution] The present invention provides a novel endo-β-N-acetylglucosaminidase (Endo-Om) using a transformant produced by cloning an endo-β-N-acetylglucosaminidase (Endo-Om) gene originated from a methanol-utilizing yeast Ogataea minuta IFO10746 strain. The Endo-Om according to the present invention has a specific activity 13-fold higher than that of known Endo-M and a Vmax value 55-fold higher than that of the known Endo-M, and is useful for the analysis of the structures of sugar chains, including composite sugar chains, in glycoproteins and the modification of the sugar chains. Also provided are an endo-β-N-acetylglucosaminidase (Endo-Cp), an endo-β-N-acetylglucosaminidase (Endo-Pa) and an endo-β-N-acetylglucosaminidase (Endo-Zr) which are produced from Candida parapolymorpha DL-1 ATCC26012 strain, Pichia anomala ATCC36904 strain and Zygosaccharomyces rouxii ATCC2623 strain, respectively, on the basis of an Endo-Om gene sequence, and each of which has a similar level of composite sugar chain cleavage activity and a similar level of composite sugar chain transfer activity to those of Endo-Om.
(FR) La présente invention concerne : une nouvelle endo-β-N-acétylglucosaminidase (Endo-Om); un gène pour l'endo-β-N-acétylglucosaminidase (Endo-Om). La nouvelle endo-β-N-acétylglucosaminidase (Endo-Om) selon la présente invention utilise un transformant produit par le clonage d'un gène endo-β-N-acétylglucosaminidase (Endo-Om) provenant d'une souche IFO10746 de levure Ogataea minuta utilisant le méthanol. L'Endo-Om selon la présente invention présente une activité spécifique 13 fois supérieure à celle de l'Endo-M connue et une valeur Vmax 55 fois supérieure à celle de l'Endo-M connue, et s'utilise pour analyser des structures de chaînes saccharides, comprenant des chaînes saccharides composites, dans des glycoprotéines, et la modification des chaînes saccharides. L'invention concerne également une endo-β-N-acétylglucosaminidase (Endo-Cp), une endo-β-N-acétylglucosaminidase (Endo-Pa) et une endo-β-N-acétylglucosaminidase (Endo-Zr)qui sont produites à partir d'une souche ATCC26012 DL-1 de Candida parapolymorpha, une souche ATCC36904 de Pichia anomala et une souche ATCC2623 de Zygosaccharomyces rouxii, respectivement, sur la base d'une séquence génique Endo-Om, chacune desquelles présentant un niveau similaire d'activité de clivage de chaîne saccharide composite et un niveau similaire d'activité de transfert de chaîne saccharide composite que celles d'Endo-Om.
(JA) 【課題】 本発明は、新規エンド-β-N-アセチルグルコサミニダーゼ(Endo-Om)及びその遺伝子を提供する。 【解決手段】 本発明は、メタノール資化性酵母Ogataea minuta IFO10746株由来のエンド-β-N-アセチルグルコサミニダーゼ(Endo-Om)遺伝子をクローニングし、形質転換株を用いて新規なエンド-β-N-アセチルグルコサミニダーゼ(Endo-Om)を提供した。本発明のEndo-Omは、公知のEndo-Mと比較して13倍もの高い比活性および55倍もの高いVmaxを有し、糖タンパク質における複合型糖鎖も含めた糖鎖構造の解析及び糖鎖修飾にとって有用である。さらに、Endo-Om遺伝子配列をもとにCandida parapolymorpha DL-1 ATCC26012株、Pichia anomala ATCC36904株、及びZygosaccharomyces rouxii ATCC2623株から、Endo-Omと同様の複合型糖鎖切断活性及び複合型糖鎖転移活性を有するエンド-β-N-アセチルグルコサミニダーゼ(Endo-Cp)、(Endo-Pa)、及び(Endo-Zr)を提供した。
