Abstract: It has been found that wild-type ferulic acid decarboxylase derived from Saccharomyces has high catalytic activity for the production of unsaturated hydrocarbon compounds. Further, it has been found that in the ferulic acid decarboxylase, substitute of the amino acid at position 398 with glutamine, methionine, asparagine, phenylalanine, histidine, or threonine more improves the catalytic activity, making it possible to provide a method capable of producing an unsaturated hydrocarbon compound such as butadiene with high productivity, and an enzyme used in the method.
