Feoforbid a oksigenaza (EC 1.14.12.20, feid a monooksigenaza, feid a oksigenaza, PAO) je enzim sa sistematskim imenom feoforbid-a,NADPH:kiseonik oksidoreduktaza (formira biladien).^[1]^[2]^[3]^[4]^[5]^[6] Ovaj enzim katalizuje sledeću hemijsku reakciju

feoforbid a + NADPH + H⁺ + O₂

\rightleftharpoons

red hlorofil katabolit + NADP⁺

This enzim katalizuje ključnu reakciju u hlorofilnoj degradaciji, do koje dolazi tokom starenja lišća i zrenja voća kod viših biljki.
