Abstract:
Dans les expériences modélisant la photosynthèse, une bonne dispersion des molécules de chlorophylle est requise. Afin d'obtenir cette bonne dispersion, une solution consiste à les ancrer à un hôte. Dans cette étude, des nouveaux matériaux hybrides sont synthétisés en utilisant des hydrotalcites et un dérivé de la chlorophylle : la chlorophylline. La chlorophylline est incorporée et dispersée dans les hydrotalcites par co-précipitation ou pendant la reconstruction des hydrotalcites. Dans cette thèse est également discuté l'effet d'une irradiation par micro-onde. Dans tous les cas sont obtenus

Abstract:
The first stage of photosynthesis involves the capture of light by pigment molecules bound within membrane-associated protein complexes. Arguably the most important of these pigments are the chlorophylls, tetrapyrrole molecules with a centrally-coordinated Mg2+ ion, a fifth ring and a long hydrophobic tail. Chlorophyll biosynthesis occurs in a stepwise manner, starting with chelation of the Mg2+ and ending with the addition of the tail via a reaction catalysed by chlorophyll synthase (CS). Then, there is handover of newly-synthesised chlorophylls to the apparatus for assembling photosynthetic

The integral membrane protein chlorophyll synthase (ChlG) catalyses the addition of the tail to the pyrrole ring.
