bin2a的全长cdna为2606bp，编码×××个氨基酸。bin2a的氨基酸序列中包括glycosyl hydrolases family ×××家族中的9段相对保守的序列，其中包括210位的活性中心glu，但是缺少另外一个活性中心，279位的glu。

This study analyzed the genetic diversity of green foxtail, yellow foxtailand foxtail millet disturbed in the North of china using twelve allozyme (21 loci),such as AATS ADHS AMPS DIAS GDH..

我们还比较了pH7.4、pH8.0、pH9.0三种pH条件下尿激酶酶切纤溶酶原生成血管抑素的反应结果，发现酶切活性在pH9.0时速度最大，pH8.0时反应速度最慢，pH7.4时反应速度介于二者之间，由此表明pH对上述酶切反应速度确实存在影响。

In the fifth part, asymmetric synthesis of β,γ-trans-alkenyl α-amino esters was achieved by chiral phosphoric acid catalyzed transfer hydrogenation of β,γ-alkynyl α-imino esters. Utilizing Hantzsch ester as the hydrogen donor, both the alkyne and imine moieties of β,γ-alkynyl α-imino esters were reduced to yield β,γ-trans-alkenyl α-amino esters with up to 96% ee.
