Protoporphyrinogen IX Oxidase PPO

Carotenoid biosynthesis, acetolactate synthase (ALS) and protoporphyrinogen IX oxidase (PPO) for herbiddes. [Pg.1200]

One relatively new herbicide is a pyrimidine-based chemical, salflufenacU (Kixor , BASF) [56]. This herbicide inhibits chlorophyll biosynthesis. In particular it inhibits protoporphyrinogen IX oxidase (PPO) in the tetrapyrrole biosynthetic pathway. Protoporphyrin IX is the heterocyUc ring system surrounding the magnesium cation in chlorophyll. There are several herbicides that operate by this mechanism. They are in group 14 (WSSA). [Pg.214]

Uracil derivatives can also function as herbicides by inhibition of the enzyme protoporphyrinogen-IX-oxidase (PRO), which is involved in the biosynthesis of chlorophyll <2006H(68)561>. Commercial examples of such PPO inhibitors include isocil 1104, bromacil 1105, terbacil 1106, flupropacil 1107, lenacil 1108, butafenacil 1109, and benzfendizone 1110 (Figure 9). [Pg.240]

Protoporphyrinogen oxidase (PPO) Catalyzes the oxidation of protoporphyrinogen IX to produce protoporphyrin IX. [Pg.401]
