查询词典 plasmid

The research work involving the expression manner of doxA gene in S. lividans TK24 with plasmid pYG57 implied that the promoter PermE may control its expression constitutively, the time for maximum expression emerged from 48 to 60 h after inoculation and cultivation and the expression level was kept relatively stable, furthermore, the recombinant hydroxylase existed mostly in mycelium cell but little in broth.

而对Tm4（pYG57）菌株中doxA基因表达方式的研究表明， dd基因在 PermE启动子控制下可能是一种组成型控制表达，其表达量在接种后培养到 48－60 h左右最高并且维持相对稳定，并且表达的柔红霉素 Cl4羟化酶主要存在于菌丝体细胞内，很少分泌到细胞外。

The SDS-PAGE electrophoresis indicated that all engineered strains containing different expression plasmid could apparently express a 45 kD band specific for daunorubicin C-14 hydroxylase.
