Two pairs of primers were designed based on the sequence of ovis aries preprochymosin cDNA reported in GenBank.The preprochymosin cDNA was obtained from toltal RNA isolated from the abomasum of 5-day-old Xinong Saanen Goat by RT-PCR method and then cloned successfully in E.coli.

However,their fluorescence emission intensities decreased by 16-22% and the ellipticity values at the negative trough increased by 13-16% for the mutants,indicating that the conformation of prochymosin was perturbed after mutation.

但它們的熒光強度下降了16-22%1024手机免费视频，在負谷中的最大橢圓值增加了13-16%av激情综合，表明突變確實給凝乳酶原的空間結(jié)構(gòu)造成了微擾。

All these results demonstrate that mutation does not cause substantial influence on the function of prochymosin and pseudochymosin with respect to autocatalytic activation.

這些結(jié)果表明突變對凝乳酶原的自我活化功能影響不大特级黄色一级无码黄色毛片在线免费观看。

Taking all the results mentioned above into consideration it is reasonable to conclude that the β-turn in the second hairpin of chymosin play a crucial role in determining the stability of prochymosin and pseudochymosin.

根據(jù)以上一系列結(jié)果久久黄色精品视频，有理由認為凝乳酶第二個β-發(fā)夾結(jié)構(gòu)的β-轉(zhuǎn)角在決定凝乳酶原和假凝乳酶的穩(wěn)定性中起至關(guān)重要的作用。
