The ribR gene in Bacillus subtilis encodes monofunctional flavin kinase, which would convert riboflavin to FMN. 枯草芽孢杆菌的ribR基因编码单功能的黄素激酶,催化核黄素转变为核黄素-5-磷酸酯。 ribR基因与其它未知功能基因构成一个操纵子,调控机制未知,通常处于不表达状态。
It is confirmed by chemical reaction that potassium malonyloxyborohydride is a new highly selective monofunctional hydroborating reagent. 通过化学反应证实,丙二酰氧基硼氢化钾是一个新的选择性高的单官能硼氢化试剂。
A monofunctional zinc acrylate and monofunctional zinc methacrylate have been prepared,the influences of which on the mechanical properties of acrylic copolymers were studied. 合成了单官能度丙烯酸锌盐和单官能度甲基丙烯酸锌盐，并研究了其对丙烯酸共聚物机械性能的影响。
H NMR and SEC analyses indicate two kinds of active species and corresponding PCL with different structures are existed in the system. Increasing the ratio of glycol to Y(OAr)3 benefits the formation of monofunctional active species. 经过1H NMR和SEC分析表明聚合体系中有两种活性中心,形成两种链结构,二醇/Y(OAr)3比值的增大有利于单钇活性中心的形成。
