(2004) (Microbiology 150, 805-816) on the basis of a partial genome sequence. In the present study, R. sphaeroides 2.4.1 was found to grow exponentially with taurine as the sole source of carbon and energy for growth. When taurine was the sole source of nitrogen in succinate-salts medium, the taurine was rapidly degraded, and most of the organic nitrogen was excreted as the ammonium ion, which was then utilized for growth. Most of the enzymes involved in dissimilation, taurine dehydrogenase (TDH), sulfoacetaldehyde acetyltransferase (Xsc) and phosphate acetyltransferase (Pta), were found to be inducible, and evidence for transcription of the corresponding genes (tauXY, xsc and pta), as well as of tauKLM, encoding the postulated TRAP transporter for taurine, and of tauZ, encoding the sulfate exporter, was obtained by reverse-transcription PCR. An additional branch of the pathway, observed by Novak et al. (2004) (Microbiology 150, 1881-1891) in R. sphaeroides TAU3, involves taurine : pyruvate aminotransferase (Tpa) and a presumptive ABC transporter (NsbABC). No evidence for a significant role of this pathway, or of the corresponding alanine dehydrogenase (Ald), was obtained for R. sphaeroides 2.4.1. The anaplerotic pathway needed under these conditions in R. sphaeroides 2.4.1 seems to involve malyl-CoA lyase, which was synthesized inducibly, and not malate synthase (GlcB), whose presumed gene was not transcribed under these conditions.</dcterms:abstract> <dc:contributor>Smits, Theo H.
