Isolation and Characterization of 3 Protochlorophyllides from Pigment Mutant C-2 A' of Scenedesmus obliquus

Kiriakos Kotzabasis and Horst Senger Fachbereich Biologie/Botanik, Philipps-Universität, Lahnberge, D-3550 Marburg, Bundesrepublik Deutschland Z. Naturforsch. 41c, 1001 — 1003 (1986); received July 1, 1986 Scenedesmus obliquus, Protochlorophyllide, Monovinyl Protochlorophyllide, Divinyl Protochlorophyllide Three Protrochlorophyllides (protochlorophyllide) were separated from mutant C-2 A' of the green alga Scenedesmus obliquus. They show distinct differences in polarity, absorption and fluorescence characteristics. Until further characteristics are established we have to assume that we found monovinyl protochlorophyllide (MV-protochlorophyllide), divinyl protochlorophyllide (DV-protochlorophyllide) and a third protochlorophyllide with different side groups. — The question whether these protochlorophyllides are intermediates in the same pathway or precursors of chlorophylls a, b and RC I in separate pathways remains open at this stage of investigation.
