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

Abstract

Abstract 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.
