An object of the present invention is to provide an agmatinase that is thermally stable and easy to handle and is useful as various reagents, a method for producing the same, and a DNA, a recombinant vector, and a transformant useful for the production of agmatinase. To do. Another object of the present invention is to provide a thermally stable agmatine detection reagent and a squid freshness measurement reagent. A protein having an agmatinase activity derived from a hyperthermophilic bacterium is thermally extremely stable. By detecting urea generated by decomposing agmatine in a test object by this agmatinase, agglutinin is quantified. It can be done easily. [Selection figure] None |
