    The biosynthesis of porphyrins by species of Athiorhodaceae by Cooper, R

    Published 1959
    “…Recent studies with enzyme systems from animals and algae have shown that colourless precursors of porphyrins, resembling the porphyrinogens produced by chemical reduction of porphyrins, are synthesised from porphobilinogen, and that chemically prepared porphyrinogens may be utilised for synthesis of other porphyrins; little is known of the properties of either the chemically prepared porphyrinogens or the biologically synthesised precursors of porphyrins.…”
