Biocatalysis of immobilized chlorophyllase in a ternary micellar system

Note:Chlorophylls are green pigments distributed in living plant cells, algae and photosynthetic bacteria (Svec, 1991). Chlorophylls can be readily converted in both in vivo and in vitro to a number of characteristic derivatives. The loss of the central magnesium ion results in the formation of pheophytin. The removal of the carboxymethyl group gives pyropheophytin, whereas the removal of ·the phytol group yields chlorophyllides and pheophorbides. Chlorophylls, pheophytins and pyropheophytins are lipophilic compounds due to the presence of ·a long chain alcohol, phytol, whereas, chlorophyllides and pheophorbides are hydrophilic ones (Rüdiger and Schoch, 1991).
