Light-dependent assimilation of trans-cinnamate by Rhodobacter sphaeroides OU5.
We present a novel light-dependent metabolism of an aromatic compound (trans-cinnamate) that is assimilatory rather than dissimilatory. Light-dependent assimilation of trans-cinnamate was observed by both growing and resting cells of Rhodobacter sphaeroides OU5. Trans-cinnamate assimilation could be correlated with simultaneous formation of both phenylalanine and tyrosine at near-stoichiometric ratios. Trans-cinnamate assimilation was promoted by carbon source and electron donors, such as glucose, pyruvate, or alpha-ketoglutarate, whereas malate, succinate, fumarate, and acetate were inhibitory.
