Effect of unsaturated fatty acids on protoporphyrinogen oxidation, a step in heme and chlorophyll synthesis in plant organelles.
Oleic acid stimulates enzymatic protoporphyrinogen oxidation by extracts of barley mitochondria and etioplasts. Greater stimulation occurred with Triton X-100 extracts which had been passed over a Sephacryl S-200 column than with crude Triton extracts, suggesting that purification may have removed a lipid factor required for optimal enzymatic activity. Palmitic acid, various phospholipids and detergents, or esters and alcohols of oleic acid did not substitute for free oleic acid. Linoleic acid caused a greater stimulation of protoporphyrinogen oxidation in both crude and purified barley organelle extracts and also caused a slow chemical oxidation of protoporphyrinogen. The stimulating effect of unsaturated fatty acids on enzymatic protoporphyrinogen oxidation may indicate a lipid requirement for this membrane bound enzyme or may also indicate involvement of unsaturated lipid oxidation in plant protoporphyrinogen oxidation.
