terminal deletion

Final results showed that the mutant with N terminal deletion of the first 7 amino acids maintained trace enzymatic activity ( less than 0.5%), while the mutant losing the first more than 8 amino acids was robbed of the enzymatic function completely.

结果表明，N末端缺失7个氨基酸的突变体几乎没有活性（小于天然活性的0.5%），N末端缺失8个以上氨基酸残基的突变体则完全丧失活性。
