Abstract
The conversion of l-glutamate to δ-aminolevulinate, in preparations of cucumber etiochloroplasts incubated in vitro, was inhibited by protoheme IX and Mg-protoporphyrin IX. Mg-protoporphyrin IX was destroyed in the presence of air and plastids; this breakdown was accelerated by S-adenosyl methionine. Mg-protoporphyrin IX was also converted to protochlorophyllide in vitro. This conversion exhibited an absolute requirement for atmospheric oxygen and was strongly stimulated by S-adenosyl methionine and by darkness.This publication has 19 references indexed in Scilit:
