Application

Application Comment Organism
biotechnology cytochrome c peroxidase as a platform to develop specific peroxygenation catalysts Saccharomyces cerevisiae

Cloned(Commentary)

Cloned (Comment) Organism
recombinant expression of wild-type and mutant enzymes Saccharomyces cerevisiae

Protein Variants

Protein Variants Comment Organism
additional information construction of three apolar distal heme pocket mutants of CcP with enhanced binding of 1-methoxynaphthalene near the heme and enhanced hydroxylation activity of 1-methoxynaphthalene Saccharomyces cerevisiae
R48A/W51A/H52A site-directed mutagenesis, the mutant shows 34fold higher activity with 1-methoxynaphthalene than the wild-type enzyme. While wild-type CcP is very stable to oxidative degradation by excess hydrogen peroxide, mutant CcP is inactivated within four cycles of the peroxygenase reaction Saccharomyces cerevisiae
R48L/W51L/H52L site-directed mutagenesis, the mutant shows higher activity with 1-methoxynaphthalene than the wild-type enzyme Saccharomyces cerevisiae
R48V/W51V/H52V site-directed mutagenesis, the mutant shows higher activity with 1-methoxynaphthalene than the wild-type enzyme Saccharomyces cerevisiae
