在批次酦酵中，使用复合培养基可得最大的核酸分解酵素产量3500 U/mL；此复合培养基之特点为含有高浓度的酵母萃出液、蛋白胴、镁离子。

The results of the crystal structure indicated that the deletion of 8 amino-acid residues from the C-terminal end of SNaseR perturbs the conformation of residue Tyr113 and blocks the binding between enzyme and substrate, which causes the biological activity of SNR141 down to 80%of wild type nuclease.

晶体结构的结果表明，从SNaseR C端切除8个残基后，扰动了残基Tyr113的构象，妨碍了酶与底物的结合，使N端片段SNR141的生物酶活力下降为天然酶的80％。
