The present invention provides a means and method useful for measurement of a glycine concentration. Specifically, the present invention provides a modified enzyme in which at least one amino acid residue is mutated so as to improve a property of a glycine oxidase which is associated with the measurement of glycine (e.g., activity of glycine oxidase for glycine, thermal stability of glycine oxidase, and substrate specificity of glycine oxidase for glycine,); and a method of analyzing glycine, comprising measuring glycine contained in a test sample using the modified enzyme; and the like.
