A tyrosinase, mTyr-CNK, that is functionally available as a monophenol monooxygenase. [PDF]

Sci Rep, 2017
AbstractTyrosinase efficiently catalyzes the ortho-hydroxylation of monophenols and the oxidation of diphenols without any additional cofactors. Although it is of significant interest for the biosynthesis of catechol derivatives, the rapid catechol oxidase activity and inactivation of tyrosinase have hampered its practical utilization as a monophenol ...

Monophenol Monooxygenase and Lincomysin Biosynthesis in Streptomyces lincolnensis [PDF]

Antimicrobial Agents and Chemotherapy, 1975
Monophenol monooxygenase (monophenol, dihydroxyphenylalanine:oxygen oxidoreductase EC 1.14.18.1) was studied in melanin-positive and melanin-negative mutants of Streptomyces lincolnensis NCIB 9413, varying in the lincomycin synthesizing ability.

Stereochemical studies on the formation of melanin by monophenol monooxygenase.

Chemical and Pharmaceutical Bulletin, 1989
The oxidation of tyrosine by monophenol monooxygenase (tyrosinase: EC 1.10.3.1) to melanin has been studied by a combination of ultraviolet, circular dichroism, and nuclear magnetic resonance techniques. It is demonstrated that the chiral intermediate (dopachrome) is generated stereoselectively in this enzymic reaction.

Possible Involvement of A Monophenol Monooxygenase in A-Factor-Dependent Yellow Pigment Production in Streptomyces griseus

Agritech, 2016
A-factor (2-isocapryloyl-3R-hydroxymethil-γ-butyro-lactone) is an essential hormonal regulator for morphological development, as well as streptomycin and yellow pigment productions in Streptomyces griseus. By UV-treatment, three mutants that were deficient in yellow pigment production but showed normal morphologiical development and strptomycin ...
