Abstract

The latices of only 13 of a total of 46 species of Ficus examined contained appreciable proteolytic activity. Therefore, high proteolytic activity in the latex is not a distinguishing feature of the genus. The latex of F. stenocarpa had the highest specific activity followed closely by the latices of F. carica and F. glabrata. Latices of 6 species of Ficus were examined by chromatography on CM-cellulose and compared with the results obtained for 9 varieties of F. carica. All of the latices were found to contain multiple proteolytic enzymes. Chromatographically, the multiple enzyme components of the several varieties of F. carica were more similar than those of the several species examined. The latices of 16 varieties of F. carica were all different as determined by free boundary electrophoresis although the specific proteolytic activity of the latices was reasonably constant.

摘要

在总共 46 种榕属植物中，仅有 13 种植物的乳汁含有可观的蛋白水解活性。因此，乳汁中具有高蛋白水解活性并不是该属的特征。榕属植物中，榕果小榕的乳汁比活力最高，其次是榕属植物的榕果和榕属植物的光叶榕。对 6 种榕属植物的乳汁进行了 CM-纤维素层析分析，并与对 9 种榕属植物的榕果变种的结果进行了比较。所有乳汁均被发现含有多种蛋白水解酶。在层析上，几种榕属植物变种的多种酶成分比几种被检查的植物种更为相似。尽管乳汁的特定蛋白水解活性相当恒定，但通过自由边界电泳测定，16 种榕属植物的榕果变种均不同。
