- primarni fluorscent hlorofil katabolit + NADP+ red hlorofil katabolit + NADPH + H+
Degradacija hlorofila je karakteristični simptom starenja lišća i sazrevanja voća. Za reakciju koju katalizuje ovaj enzim neophodan je redukovani feredoksin, koji se formira bilo putem NADPH u putu pentoznog-fosfata ili dejstvom fotosistema I. Ova reakcija se odvija bez otpuštanja supstrata iz EC 1.14.12.20, feoforbid a oksigenaze.
