Vector-ZaTdT-K337A-KanR

Description

To obtain the desired saturation mutagenesis, oligonucleotide primers were designed with degenerate codons. In addition, each single-site saturation mutant was generated according to the PCR-based QuickChange method. The PCR was performed according to the operation manual. The PCR product was digested with DpnI restriction enzyme and transformed into E.coli DH5-alpha competent cells.We will extract the plasmid and sequence it to make sure the mutation was successful.

Experiment

SDS-PAGE of ZaTdT-K337A

We transfected the Sequencing is correct ZaTdT-K337A plasmid into E.coli BL21(DE3) competent cell. After overnight, an appropriate colony was used to express the mutant protein and verify its activity

Catalytic activity assay of ZaTdT-K337A

We transfected the Sequencing is correct ZaTdT-K337A plasmid into E.coli BL21(DE3) competent cell. After overnight, an appropriate colony was used to express the mutant protein and verify its activity
