Abstract excerpt
Microbial transglutaminase (MTG) gene (mtg) from Streptomyces hygroscopicus H197 strain was cloned by PCR and mutated by deleting a specific 84 bp fragment using overlapping extension PCR. The mutant MTG and the wild MTG genes expressed by recombinant plasmid pET32a+- mutant mtg and pET32a+ -mtg, respectively, and were harvested by alternating freeze-thaw steps and purified by Ni column. The purified mutant MTG...
