AJC7/S125D/ H342L

AJC7 two-point mutant

Construction

The mutation site of H342L is located far from S125D, allowing for the direct construction of the S125D/T181A double mutant using pET-28a(+)-AJC7-S125D as a template along with the primers designed for single-point mutation as outlined in [Design 1]. Following the mutation, the PCR products were verified using nucleic acid gel electrophoresis. The plasmids that exhibited the correct bands were subsequently transformed into E. coli BL21 (DE3) competent cells.
