polyphenolase/モロコシ属

Green shoots and first internodes of Sorghum vulgare var. Wheatland milo contain three phenoloxidase activities separable by means of Sephadex G-100 gel filtration. Two of these are found only in green leaves. I, eluted at the void volume and presumably a high molecular weight form, has both

A p-hydroxycinnamic acid oxidase activity was present in enzyme preparations from first internodes of Sorghum vulgare variety Wheatland milo when incubated in phosphate buffer at pH 7.5. This preparation had no classical polyphenolase activity but had both peroxidase and catalase activities. Since
