recombinant enzyme expression in Escherichia coli
-
the sequence motif is introduced into a mesophilic Escherichia coli isopropylmalate dehydrogenase, one by one. The introduction of the whole motif leads the mesophilic enzyme to be more unstable whereas substitution of only one amino acid residue in the motif thermostabilizes the enzyme
-
wild type and mutant leuB genes are overexpressed in Escherichia coli
