It was found that components such as Na_2SO_4 and sodium dodecy 1-benzensulfonate reduce the activity, while nonionic surfactants and oxidation bleaching agents enhance the activity sizably. The kinetic mechanism of the enhancement by nonionic surfactants is discussed in terms of the decreased dissociation constants between the enzyme/micelle complex and substrate, casein. The enhancement of the activities of alkali proteases by oxidation bleaching agents, namely, sodium perborate, sodium percarbonate and hydrogen peroxide has been studied by the modified casein-Folin method and gel permeation chromatography (GPC). It was found that casein is degraded by the oxidizing agents to fragments with ca. 10,000 dalton, which are hydrolysed to smaller fragments by the enzyme, faster than casein itself. These investigations suggest importance of investigating the enzyme activities under the practical conditions they are used., 5, KJ00004311035, 論文, Article}, pages = {9--24}, title = {洗剤成分によるアルカリプロテアーゼの活性上昇}, volume = {1}, year = {1991}, yomi = {オノザワ, ハルコ and シモムラ, クミコ} }
