Characterization of 3-Acetyl Chlorophyll a and 3-Acetyl Protochlorophyll a Accommodated in the B800 Binding Sites of Photosynthetic Light-Harvesting Complex 2 in the Purple Photosynthetic Bacterium Rhodoblastus acidophilus.
We present the detailed characterization on the reconstitution of two cyclic tetrapyrrole pigments that have the same substituents but differ in the degree of hydrogenation in the macrocycles from bacteriochlorophyll (BChl) a (7,8,17,18-tetrahydroporphyrin) into the binding sites of B800 BChl a in light-harvesting complex 2 (LH2) of purple photosynthetic bacteria. Both 3-acetyl chlorophyll (Chl) a (17,18-dihydroporphyrin) and 3-acetyl protochlorophyll (PChl) a (porphyrin) were inserted into the B800-binding pockets in LH2, indicating that these pockets allow alteration of the degree of hydrogenation in the cyclic tetrapyrroles.

Polyethylene-based high-performance liquid chromatography of chloroplast pigments: resolution of mono- and divinyl chlorophyllides and other pigment mixtures.
In addition to most chlorophylls and their derivatives, monovinyl and divinyl chlorophyll species were separated by high-performance liquid chromatography, using a polyethylene column and a simple elution with aqueous acetone. Peak retention and resolution of the pigment separation were greatly increased by increasing the polarity of the mobile phase and also by decreasing the column temperature. Polyethylene chromatography showed chlorophyll separation behavior similar to that of the octadecyl silica column, but it showed no adsorption of the pigment species containing free carboxylic acid groups, enabling the complete separation of chlorophylls and their derivatives. Polyethylene is a superior alternative stationary phase to the known reversed-phase materials for chlorophyll separation and analysis.
