(S)-norcoclaurine synthase.
based on mapping to UniProt Q67A25
Dopamine + 4-hydroxyphenylacetaldehyde = (S)-norcoclaurine + H(2)O.
-!- The reaction makes a 6-membered ring by forming a bond between C-6 of the 3,4-dihydroxyphenyl group of the dopamine and C-1 of the aldehyde in the imine formed between the substrates. -!- The product is the precursor of the benzylisoquinoline alkaloids in plants. -!- Will also catalyze the reaction of 4-(2-aminoethyl)benzene-1,2-diol + (3,4-dihydroxyphenyl)acetaldehyde to form (S)-norlaudanosoline, but this alkaloid has not been found to occur in plants.
