aspartic proteases 中文意思是什麼
-
Dna sequence analysis showed that the cloned nk gene was highly homologous to the sequence reported by nakamura. the deduced amino acid sequence also had the conserved sequences ( serine 221, histidine 64, and aspartic acid 32 ) which was essential for the catalytic center of serine proteases. the nk gene was then cloned into the transfer vector pvl1393
本實驗以b . subtilis （ natto ）基因組dna為模板擴增了nk基因，測序結果顯示與nakamura報道的納豆激酶基因高度同源，其氨基酸序列也含有絲氨酸蛋白酶的活性保守中心（ serine221 ， histidine64 ， asparticacid32 ） 。 -
All proteases use water to cut their respective proteins, and enzymes in the aspartyl protease family employ a pair of aspartic acids to activate a water molecule for this purpose
所有的蛋白酶都會利用水來切割其作用的蛋白質，而天冬胺酸蛋白酶家族的成員，則還會利用兩個天冬胺酸分子來活化水分子，以利蛋白質的切割。
