An intermediate in the phytylation of chlorophyllide-a in vivo

The chromatogram of the extract from etiolated bean leaves illuminated for 1 min showed a single peak of chlorophyllide a. On subsequent dark incubation of the leaves for 5 min, an intermediate band appeared in the chromatogram. During 2 hr of incubation, the content of the intermediate first increased, then decreased and was finally transformed completely to chlorophyll a.
