General annotation (Comments)

Function	This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds By similarity. UniProtKB Q92396
Catalytic activity	L-tyrosine + L-dopa + O2 = L-dopa + dopaquinone + H2O. Ref.1
Cofactor	Binds 2 copper ions per subunit. Ref.1
Subunit structure	Monomer. Ref.1
Post-translational modification	The N-terminus is blocked. Ref.1
Sequence similarities	Belongs to the tyrosinase family.
Biophysicochemical properties	Kinetic parameters: KM=1930 µM for L-dopa Ref.1 KM=119 µM for t-butylphenol Ref.1 KM=30.6 µM for p-cresol Ref.1 KM=163 µM for t-butylcatechol Ref.1 KM=1240 µM for 3-(3,4-dihydroxyphenyl) propionic acid Ref.1 KM=122 µM for dopamine Ref.1
