With chlorophyll pigments from prolamellar bodies to light‐harvesting complexes

摘要: The biosynthetic chain leading from 5-aminolevulinic acid to chlorophyll is localised the plastid. Many of enzymes are nuclear-encoded. NADPH-protochlorophyllide oxidoreductase (EC 1.3.1.33) one such enzyme which encoded by two different genes and can exist in an A a B form. Its import into plastid seems be facilitated when protochlorophyllide present chloroplast envelope. Within reductase assembled thylakoids or prolamellar bodies. specific properties together with lipids etioplast inner membranes promote formation three-dimensional regular network forms ternary complex NADPH that gives rise spectral protochlorophyllide. Light transforms chlorophyllide this photoreaction induces conformational change protein leads process disaggregation enzyme, pigment aggregates membranes, followed spectroscopically electron microscopy. newly formed esterified membrane-bound nuclear-encoded synthase molecule then associated proteins active complexes photosynthetic machinery.
