Abstract excerpt
Introduction of the bchP gene from Rhodobacter sphaeroides encoding geranylgeranyl reductase into Rhodospirillum rubrum alters the esterification of the bacteriochlorophylls so that phytol is used instead of geranylgeraniol. The resulting transconjugant strain of Rs. rubrum grows photosynthetically, showing that phytolated Bchla can substitute for the native pigment in both the reaction center (RC) and the...
