Abstract
Induced-transport tests with comparatively undegraded rabbit liver phosphoglucomutase show that the enzyme possesses a phosphoenzyme mechanism and that any interconversion of phosphoenzyme forms is very rapid. A relatively stable 32P-labelled phosphoenzyme was isolated, which exchanged label rapidly with substrates. The phospho group appears to be bonded to a serine residue on the enzyme.
摘要
用相对未降解的兔肝磷酸葡萄糖变位酶进行的诱导转运试验表明，该酶具有磷酸化酶机制，并且磷酸化酶形式的任何相互转化都非常迅速。分离出一种相对稳定的32P标记的磷酸化酶，它能与底物快速交换标记。磷酸基团似乎与酶上的一个丝氨酸残基结合。
