(1)从淡水魚青魚腸胃道中提取出魚蛋白酶,酶制剂活力以酪蛋白作底物約为結晶胰蛋白酶的1/3。酶的前身有酶原存在,激活最适pH为8。(2)酶作用的pH偏于碱,水解酪蛋白和B-精-NH_2的最适pH都为9,酶和酶原对酸都不稳定,当pH低于4吋,酶活性和酶原激活的能力迅速丧失。(3)此酶对热很稳定,反应温度55度时,反应速度仍符合Arrhenius定律。測得水解酪蛋白和B-精-NH_2的活化能分别为14.6千卡/克分子及8.0千卡/克分子,較之胰蛋白酶水解此同一底物所需的活化能为低,尤以后者更显著,約相当于1/2值。(4)对小底物的水解以B-精-NH_2活力最高,K_m=3.3×10~(-3)M(40度pH8.7),为胰蛋白酶水解此同一底物所得K_m值的二分之一,对胰凝乳蛋白酶的底物B-酪-NH_2不作用,而对Cbz-甘-苯丙及白-NH_2却有較明显的活力。(5)半胱氨酸(10~(-3)M)和PCMB(10~(-4)M)对酶活力无影响,但能被DFP和胰蛋白酶抑制剂所抑制。DFP的抑剂随其与酶保温时間的增长而增大。lO~(-4)MDFP与酶液保溫10小时后能抑制酶活力达60%。胰蛋白酶抑制剂对此酶抑制的作...

Bromoacetate and iodoacetate have been found to be strongly inhibitory to the activity of papain at pH 5 even in the presence of excess cysteine; the activity of the enzyme for the hydrolysis of benzoyl arginine amide, leucinamide or haemoglobin was completely suppressed when the molar ratio of inhibitor/enzyme reached 0.5. The content of sulphydryl groups of the enzyme was not changed after the inhibition by bromoacetate have reached completion under these conditions. Papain thus carboxymethylated can still be crystallized like the unmodified enzyme.The rate of reaction between bromoacetate and papain was greatly lowered in 6 M urea; both the substrate, leucinamide, and the inhibitor p-chloromercuri-benzoate, were effective in the protection of the enzyme against the action of bromoacetate. It appears therefore, that the ability of papain to react with bromoacetate is closely related to the catalytic activity of the enzyme, and bromoacetate acts, most probably, at the active site of the enzyme.The amino acid compositions of papain, carboxymethyl papain, ribonuclease, carboxymethylribonuclease prepared according to Gundlach et al., have been analyzed by two-dimensional paper electrophoresis-paper chromatography and compared with S-carboxymethyl cysteine and Im-carboxymethyl histidine. The results showed that histidine but not cysteine was the point of attack by bromoacetate at the active site of papain under the above conditions.

(1)在过量半胱氨酸存在下微量溴代乙酸或碘代乙酸在pH5对木瓜蛋白酶有強烈的抑制作用,当抑制剂与酶的克分子比为0.5时,抑制即达完全。抑制前后木瓜蛋白酶巯基含量不变。溴代乙酸作用后所得到的羧甲基木瓜蛋白酶汞盐結晶,与木瓜蛋白酶汞盐結晶相同。(2)在6M尿素溶液中溴代乙酸与木瓜蛋白酶的作用速度显著降低,底物L-白氨酰胺及抑制剂对氯汞苯甲酸都具有保护作用。这些事实表明溴代乙酸的抑制与木瓜蛋白酶的催化活性有密切关系,其作用点很可能是活性中心所在。(3)以双相电泳层析进行氨基酸組成分析結果指出,溴代乙酸作用点很可能是組氨酸殘基。
