Cloning, construction of prokaryotic expression vector and expression ofEscherichia coli cytosine deaminase gene
Cytosine deaminase gene ofEscherichia coli strain H-30 was cloned, and its initiation codon of ‘GTG’ was mutated to ‘ATG’ by PCR. Prokaryotic recombinant expression vector pBV220-CD was constructed. Clone with hi...
