Abstract
The previously reported isoenzymes of sweet-potato glucose 6-phosphate isomerase were resolved by DEAE-cellulose chromatography. The multiple forms exhibited identical electrophoretic properties and electrofocused as a single component with an apparent isoelectric pH of 4.0. Chromatographic studies also suggest that the multiple forms do not represent true isoenzymes.
摘要
先前报道的甘薯葡萄糖6-磷酸异构酶的同工酶通过DEAE-纤维素色谱法进行了分离。这些多种形式表现出相同的电泳性质，并在等电聚焦时作为单一成分聚焦，表观等电pH值为4.0。色谱研究还表明，这些多种形式并不代表真正的同工酶。
