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.

The aggregation of chlorophyll a

Archives of Biochemistry and Biophysics, 1964
Abstract 1. 1. Aggregation of chlorophyll a in various nonpolar solvents has been demonstrated, and from the IR spectra the probable site of the hooking together of the molecules has been deduced. 2. 2. If chlorophyll a exists in the cell in a completely nonpolar milieu (as the visible spectroscopic studies suggest), then CCl4 solutions of ...

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 ...

Chlorophyll metabolism

Current Opinion in Plant Biology, 2006
Since the 1970s, researchers have proposed several regulatory pathways governing chlorophyll metabolism, but only recently have the underlying molecular mechanisms been elucidated. The recent data indicate that such regulatory systems are more complex than originally anticipated.

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.
