Chlorophylls, Symmetry, Chirality, and Photosynthesis

Symmetry, 2014
Chlorophylls are a fundamental class of tetrapyrroles and function as the central reaction center, accessory and photoprotective pigments in photosynthesis. Their unique individual photochemical properties are a consequence of the tetrapyrrole macrocycle,

Chlorophyll-chlorophyll and chlorophyll-water interactions in the solid state

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1972
Abstract Absorption spectra in the visible and infrared have been recorded for films of dry chlorophyll a , chlorophyll b , bacteriochlorophyll, pyrochlorophyll a , and pheophytin a . The effects of water on the spectra have also been studied.

Chlorophyll synthetase in chlorophyll-free chromoplasts

Plant Cell Reports, 1981
A considerable incorporation of [1-(14)C]isopentenyl diphosphate into chlorophyll in chromoplast preparations from daffodil flowers (Narcissus pseudonarcissus L.) was observed when exogenous chlorophyllide a was added. The enzyme chlorophyll synthetase showed properties of a peripheral membrane protein.

Organization of chlorophyll biosynthesis and insertion of chlorophyll into the chlorophyll-binding proteins in chloroplasts

Photosynthesis Research, 2015
Oxygenic photosynthesis requires chlorophyll (Chl) for the absorption of light energy, and charge separation in the reaction center of photosystem I and II, to feed electrons into the photosynthetic electron transfer chain. Chl is bound to different Chl-binding proteins assembled in the core complexes of the two photosystems and their peripheral light ...

Biosynthesis of chlorophyll b and the chlorophyll cycle

Photosynthesis Research, 2002
Recent progress in the knowledge of chlorophyll b biosynthesis from chlorophyllide a and reduction of chlorophyll b to chlorophyll a is described. The minireview includes a description of the enzymes involved in these reactions and, where appropriate, of the genes encoding these enzymes.
