The apparent affinity constants for the binding of Cs+, Rb+, K+, Li+, Tl+ and NH4+ to (Na+ + K+)-dependent adenosine triphosphatase from teleost gills were measured and the values discussed in terms of the ion-selectivity isotherm described by Eisenman & Krasne (1975) [in MTP International Review of Science: Biochemistry Series One (Fox, C.F., ed.), vol. 2, pp. 27--59, Butterworths University Park Press, Baltimore]. The ion selectivity of the present enzyme is remarkably similar to that from nerve and brain.
测定了铯离子(Cs⁺)、铷离子(Rb⁺)、钾离子(K⁺)、锂离子(Li⁺)、铊离子(Tl⁺)和铵离子(NH₄⁺)与硬骨鱼鳃中(钠离子 + 钾离子)依赖的三磷酸腺苷酶结合的表观亲和常数,并根据艾森曼和克拉斯内(1975年)[载于《MTP国际科学评论:生物化学第一系列》(福克斯,C.F.编),第2卷,第27 - 59页,巴特沃思大学公园出版社,巴尔的摩]所描述的离子选择性等温线对这些值进行了讨论。本酶的离子选择性与神经和大脑中的离子选择性非常相似。
