Abstract
Using an immunosorbent, a new form of transketolase, namely, an enzyme-RNA complex, was isolated from a baker's yeast extract. Spontaneous fission of RNA (or its enzymic hydrolysis by RNase) is accompanied by a sharp increase in the catalytic activity of transketolase, which may be directly related to the enzyme's regulation mechanism.
摘要
利用免疫吸附剂，从面包酵母提取物中分离出一种新形式的转酮醇酶，即一种酶 - RNA复合物。RNA的自发裂变（或其被核糖核酸酶的酶促水解）伴随着转酮醇酶催化活性的急剧增加，这可能与该酶的调节机制直接相关。
