Abstract

Genes thought to encode (a) the regulator of taurine catabolism under carbon-limiting or nitrogen-limiting conditions and (b) taurine dehydrogenase were found in the genome of Rhodopseudomonas palustris. The organism utilized taurine quantitatively as a sole source of nitrogen (but not of carbon) for aerobic and photoheterotrophic growth. No sulfate was released, and the C-sulfonate bond was recovered stoichiometrically as sulfoacetate, which was identified by mass spectrometry. An inducible sulfoacetaldehyde dehydrogenase was detected. R. palustris thus contains a pathway to generate a natural product that was previously believed to be formed solely from sulfoquinovose.
