Considerations about the kinetic mechanism of tyrosinase in its action on monophenols: A review

•Tyrosinase can hydroxylate a broad range of monophenols.•In Type A substrates, the o-quinone evolution generates o-diphenol in the medium.•In Types B, C and D substrates, the evolution does not accumulate o-diphenol.•Hydrogen peroxide transforms Em to Eox and the enzyme has hydroxylating activity.•In presence of monophenols, Michaelis constant for oxygen is very low.
