The phosphocarrier protein (HPr) of the phosphoenol pyruvate : alpha-methyl-D-glucoside-phosphotransferase system (PTS) has been purified from Bacillus subtilis Marburg 168. The molecular weight is about 8300. HPr contains 1 histidine residue. Phophoenzyme I appears to be an intermediate in the initial phosphoryl transfer from phosphoenolpyruvate (PEP) to HPr. Phospho-HPr is isolated and characterized as a component of the complete system.
α-甲基-D-葡萄糖苷磷酸转移酶系统(PTS)的磷酸载体蛋白(HPr)已从枯草芽孢杆菌马伯格168株中纯化出来。其分子量约为8300。HPr含有1个组氨酸残基。磷酸酶I似乎是磷酸烯醇丙酮酸(PEP)向HPr进行初始磷酰基转移的中间体。磷酸化HPr被分离出来并被鉴定为完整系统的一个组成部分。
