Cloned(Commentary)

Cloned (Comment) Organism
wild-type enzyme and mutant enzymes C255S and C255M, expression in Escherichia coli Pseudomonas sp.

Protein Variants

Protein Variants Comment Organism
C255M high resistance to inactivation by Hg2+, increase of enzyme stability at 25°C, decrease of thermostability above 45°C. Native enzyme preserves more than 80% of initial activity after 2 h in 7 M urea. The mutant enzyme is completely inactive Pseudomonas sp.
C255S high resistance to inactivation by Hg2+, increase of enzyme stability at 25°C, decrease of thermostability above 45°C. Native enzyme preserves more than 80% of initial activity after 2 h in 7 M urea. The mutant enzyme is completely inactive Pseudomonas sp.
