ID   4.1.1.108
DE   4-hydroxyphenylacetaldehyde synthase.
CA   L-tyrosine + O2 + H2O + H(+) = (4-hydroxyphenyl)acetaldehyde + H2O2 +
CA   NH4(+) + CO2.
CC   -!- The enzyme, isolated from the the plant Petroselinum crispum
CC       (parsley), catalyzes the production of 4-hydroxyphenylacetaldehyde
CC       directly from L-tyrosine.
CC   -!- Tyramine is not formed as an intermediate.
CC   -!- The enzyme has a low activity with L-dopa (cf. EC 4.1.1.107).
