An object of the present invention is to provide a uronic acid-containing glucan or a modified product thereof. The glucuronic acid-containing glucan of the present invention is a glucuronic acid-containing glucan in which a glucuronic acid residue is bound to at least one non-reducing end of a glucan, and the glucan is a branched α-1,4 glucan or a linear α-1,4 glucan. The glucuronic acid-containing glucan of the present invention can be provided by allowing α-glucan phosphorylase derived from Aquifex aeolicus VF5 to act on glucuronic acid-1-phosphate to thereby transfer a glucuronic acid residue to the non-reducing end of the receptor glucan.
摘要:
A novel ligand conjugate which is effectively utilizable for analyzing a function of a protein; a ligand-supporting object; and a method of analyzing a protein. The ligand conjugate has a structure which comprises: a linker compound having a structure represented by the following General Formula (1):
(wherein n and p each is an integer of 0 to 6) in which X is a structure comprising one, two, or three hydrocarbon derivative chains which have an aromatic amino group at the end and may have a carbon-nitrogen bond in the main chain, Y is a hydro-carbon structure containing one or more sulfur atoms, and Z is a straight-chain structure comprising a carbon-carbon bond or carbon-oxygen bond; and a sugar which has a reducing end and is bonded to the linker compound through the aromatic amino group.
摘要:
It is intended to provide a stable novel sugar-immobilized metal nanoparticle capable of easily immobilizing a sugar chain, a method for measuring sugar-protein interaction easily and at a low cost using the same without labeling, and a method for simply recovering a protein from a sugar-protein interactant. A maltose-immobilized gold nanoparticle was obtained by binding a ligand complex, in which maltose and a linker compound had been bound to each other, to a gold nanoparticle. By adding this maltose-immobilized gold nanoparticle to a dilution series of concanavalin A, a sugar-protein interactant of maltose and ConA was formed, and red-purple color derived from a colloidal solution of maltose-immobilized gold nanoparticle disappeared. That is, sugar-protein interaction could be confirmed by visual observation without labeling.
