Abstract:
The CRISPR gene editing technology is simple in design and highly efficient, making it the most widely used gene editing tool today. At present, CRISPR gene editing technology has shown a certain application value in enzyme development, but its application potential has not been fully developed. CRISPR gene editing technology can not only be used to knockin enzyme genes and knockout genes that are not conducive to enzyme expression, but can also be applied to single-base editing of enzyme genes, tandem sgRNA for multi-enzyme gene editing, sgRNA library for enzyme screening, endogenous enzyme gene modification, transcriptional activation or inhibition of enzyme gene expression, and fluorescence imaging of enzyme genes. Especially, this review innovatively proposes for the first time that CRISPR gene editing technology can be used for site specific fusion of enzyme genes, cell surface display of endogenous enzymes, and knockin of super long DNA for simultaneous expression of multiple enzymes, providing new ideas for maximizing the value of CRISPR gene editing technology in enzyme development in the future.
