Phenol oxidase from Penetrocephalus ganapatii

Table 7.5. Effect of various inhibitors on the phenol oxidase of Penetrocephalus ganapatii. (Data from Jayabaskaran Ramalingam,...

A phenol oxidase from the fish cestode, Penetrocephalus ganapatii, has been characterised bio-chemically and has been shown to have a pH optimum of 7.4 (Fig. 7.9) (362). Its activity with three different substrates, dopamine, adrenaline (= epinephrine) and dopa are shown in Table 7.4 and Fig. 7.10 the action of various inhibitors is shown in Table 7.5. The Michaelis constant for dopamine was 189 p.M and the enzyme was stable between 20 and 40°C. The action of various inhibitors was also studied.
