Cloned (Comment) Organism
overexpression of V75M in Escherichia coli with or without an N-terminal histidine-tag Pyricularia oryzae

Protein Variants

Protein Variants Comment Organism
V75M inhibition of the mutant enzyme by (1RS,3RS)-2,2-dichloro-N-[(R)-1-(4-chlorophenyl)ethyl]-1-ethyl-3-methylcyclopropanecarboxamide is more than 200fold reduced in comparison with that of the wild-type, about 2fold reduced turnover number for scytalone as compared to wild-type enzyme Pyricularia oryzae
