Activity and CD characteristics of mutated and truncated forms of Str enolase.

ND = not determined,
* The standard errors as a percentage of the activity for these samples are high because the concentration of protein in the assays is very high and there is reactivation of the enolase during the assay.
Activity and CD characteristics of mutated and truncated forms of Str enolase.

ND：未测定（not determined）
* 本类样本以活性百分比计的标准误偏高，系因测定体系内蛋白质浓度极高，且测定过程中烯醇化酶会发生再激活。
