PROBLEM TO BE SOLVED: To provide a method for producing L-threo-3-(3,4-dihydroxyphenyl)serine in a high yield and in a high purity. SOLUTION: This method for producing L-threo-3-(3,4-dihydroxyphenyl)serine is to enzymatically hydrolyzing racemic threo-3-(3,4-methylenedioxyphenyl)serine (in which, the amino acid group is protected with a phenylacetyl group substituted optionally at its benzene ring) by using a penicillinacylase.
