Шаблон:Short description Шаблон:Infobox enzyme Beta-carotene 3-hydroxylase (Шаблон:EC number, beta-carotene 3,3'-monooxygenase, CrtZ) is an enzyme with systematic name beta-carotene,NADH:oxygen 3-oxidoreductase .[1][2][3][4][5][6][7] This enzyme catalyses the following chemical reaction

beta-carotene + 2 NADH + 2 H+ + 2 O2 <math>\rightleftharpoons</math> zeaxanthin + 2 NAD+ + 2 H2O (overall reaction)
(1a) beta-carotene + NADH + H+ + O2 <math>\rightleftharpoons</math> beta-cryptoxanthin + NAD+ + H2O
(1b) beta-cryptoxanthin + NADH + H+ + O2 <math>\rightleftharpoons</math> zeaxanthin + NAD+ + H2O

Beta-carotene 3-hydroxylase requires ferredoxin and Fe(II).
