Abstract: It is intended to provide a method of refolding an inactive protein which is produced by Escherichia coli or the like and the higher-order structure of which is still unformed or a protein which has been activated due to a change in its three-dimensional structure for some reason, etc. Namely, a method comprising treating an inactive protein which is produced by Escherichia coli or the like and the higher-order structure of which is still unformed or a protein which has been activated due to a change in its three-dimensional structure for some reason with zeolite beta to thereby impart the inherent function or activity to the protein; a refolding kit; a refolding agent and a molded article; and a method of producing an active protein with the use of the same. Thus, it is possible to provide a novel method of activating protein function that is excellent in versatility and universality, can be conveniently and easily carried out, is less expensive and allows repeated use of a function activator, compared with the existing methods.

Abstract: Disclosed are a high silica zeolite having a novel crystal structure, a zeolite membrane and methods for producing them. The zeolite is represented by the chemical composition:[(Si36-xTy·O72)·Mz] (wherein M represents a cation of an alkali metal such as Li, Na, K and Rb; T represents Al, Ga, Fe and Ce as skeleton substituting elements; and x satisfies 0 ≤ x ≤ 3.0, y satisfies 0 ≤ y ≤ 1.0, and z satisfies 0 ≤ z ≤ 3.0), and has a micropore composed of a covalent bond of Si-O. The zeolite has a specific diffraction peak at 2θ in the powder x-ray diffraction pattern.

Abstract: The present invention provides a method for refolding protein produced, for example, by Escherichia coli, that is inactive due to an as yet unformed higher order structure, or protein deactivated due to a change in conformation for some reason. The invention comprises a method, refolding kit, refolding agent, and molding that activate a native function or activity inherent to a protein through treatment with zeolite beta of protein produced, for example, by Escherichia coli, that is inactive due to an as yet unformed higher order structure, or protein deactivated due to a change in conformation for some reason. The invention also comprises a method for producing an active protein that utilizes the same. As compared with conventional methods, the present invention can provide a novel method for activating protein function that is highly versatile and generalizable, that employs a simple and easy protocol, and that is inexpensive and enables repeated use of the function activator.
