Rhodobacter sphaeroides grown in the presence of nicotinamide excreted bacteriochlorophyll precursors, 2,4-divinyl protochlorophyllide (DV-Pchlide) and a small amount of 2-monovinyl protochlorophyllide (MV-Pchlide). Accumulation of these pigments indicates that nicotinamide inhibited the bacteriochlorophyll biosynthetic pathway site-specifically between DV-Pchlide and MV-Pchlide. This phenomenon is also observed in an aerobic photosynthetic bacterium, Erythrobacter sp. OCh 114. Among 12 nicotinamide derivatives and isomers tested, only nicotinamide was effective, indicating that in addition to the completeness of the pyridine ring skeleton at positions 1 to 3, the carboxylic acid amide group is essential for this inhibition. The technique described in this report permits the simple preparation of large quantities of DV-Pchlide.
