Abstract
- Flavokinase isolated from 18-day chick embryo liver shows optimal activity at pH 8.6, in the presence of the divalent cations Zn2+, Ca2+ and Mn2+. 2. The activity and stability of flavokinase depends on the RBP concentration. 3. Interaction between flavokinase and riboflavin binding protein was demonstrated by means of crossed immunoelectrophoresis and affinity chromatography.
摘要
- 从18日龄鸡胚肝脏中分离出的黄素激酶在pH 8.6、存在二价阳离子Zn2+、Ca2+和Mn2+的情况下表现出最佳活性。2. 黄素激酶的活性和稳定性取决于视黄醇结合蛋白（RBP）的浓度。3. 通过交叉免疫电泳和亲和色谱法证明了黄素激酶与核黄素结合蛋白之间的相互作用。
