Reaction: 1-(4-hydroxyphenyl)-2-aminoethanol = (4-hydroxyphenyl)acetaldehyde + NH3
Glossary: octopamine = 1-(4-hydroxyphenyl)-2-aminoethanol
Other name(s): octopamine hydrolyase; octopamine hydro-lyase (deaminating)
Systematic name: 1-(4-hydroxyphenyl)-2-aminoethanol hydro-lyase [deaminating; (4-hydroxyphenyl)acetaldehyde-forming]
Comments: The enzyme-catalysed reaction is believed to be dehydration to an enamine, which is spontaneously hydrolysed to an aldehyde and ammonia.
