Template:Infobox enzyme The enzyme (S)-norcoclaurine synthase (Template:EnzExplorer) catalyzes the chemical reaction
- 4-hydroxyphenylacetaldehyde + 4-(2-aminoethyl)benzene-1,2-diol (Dopamine) (S)-norcoclaurine + HTemplate:SubO

This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is 4-hydroxyphenylacetaldehyde hydro-lyase [adding dopamine (S)-norcoclaurine-forming]. Other names in common use include (S)-norlaudanosoline synthase, and 4-hydroxyphenylacetaldehyde hydro-lyase (adding dopamine). This enzyme participates in benzylisoquinoline alkaloid biosynthesis.
