EC 4.1.1.108 Details
show Brenda entryEC number
4.1.1.108
Accepted name
4-hydroxyphenylacetaldehyde synthase
Reaction
L-tyrosine + O2 + H2O = (4-hydroxyphenyl)acetaldehyde + CO2 + NH3 + H2O2
Other name(s)
TYRDC-2 (gene name)
Systematic name
L-tyrosine carboxy-lyase (oxidative-deaminating)
Comment
A pyridoxal 5′-phosphate protein. The enzyme, isolated from the the plant Petroselinum crispum (parsley), catalyses the production of 4-hydroxyphenylacetaldehyde directly from L-tyrosine. Tyramine is not formed as an intermediate. The enzyme has a low activity with L-dopa (cf. EC 4.1.1.107, 3,4-dihydroxyphenylacetaldehyde synthase).
