Part:BBa_K5520004

pT7-LacO-His-CDA

This part contains BBa_K2406020, BBa_B0034, BBa_K5520002 and BBa_K731721. BBa_B0034 contains a natural ribosome binding site (RBS) to facilitate the expression of downstream genes. By inducing efficient expression of the CDA protein through the addition of IPTG, the protein can subsequently be purified using the His tag for further enzyme activity tests and product polymerization.

Usage and Biology

Plasmid construction PET-28a linearized vector (5371 bp) was amplified using PET-28a plasmid from the laboratory conserved as template and ZT-F and ZT-R as primers. Using CDA-F and CDA-R as primers, we amplified PET-28a-CDA as a vector using Gibson assembly. The T7 promoter、RBS、 lac operator, CDA gene, 6×His tag, kana antibiotic gene, and T7 terminator on the vector PET-28a were already inserted before experiments.
