ecdysone 20-monooxygenase activity

Known as: alpha-ecdysone C-20 hydroxylase activity, ecdysone 20-hydroxylase activity, ecdysone,hydrogen-donor:oxygen oxidoreductase (20-hydroxylating) 
Catalysis of the reaction: AH(2) + Ecdysone + O(2) = 20-hydroxyecdysone + A + H(2)O. [EC:1.14.99.22, RHEA:14024]
