Unification for the expression of the monophenolase and diphenolase activities of tyrosinase.
In order to unify and generalize, we define the International Units used to express the monophenolase and diphenolase activity of mushroom tyrosinase acting on different monophenol/diphenol pairs and establish a quantitative relation. Similarly, the activity units to express tyrosinase activity proposed by suppliers are discussed and compared with the above International Units. Lastly, we study the relation between International Units of diphenolase activity and of monophenolase activity for other biological sources of tyrosinase.
