Zusammenfassung
Klebsiella oxytoca TauN1 represents a group of isolates which utilise taurine (2-aminoethanesulfonate) quantitatively as a sole source of combined nitrogen for aerobic growth. During growth, a compound is excreted, which has now been identified as isethionate (2-hydroxyethanesulfonate). An ion-chromatographic separation of isethionate was developed to quantify the putative isethionate, whose identity was confirmed by matrix-assisted, laser-desorption ionisation time-of-flight mass spectrometry. Strain TauN1 utilised taurine (and excreted isethionate) concomitantly with growth. Cell-free extracts contained inducible taurine transaminase, which yielded sulfoacetaldehyde. A soluble, NADP-dependent isethionate dehydrogenase converted sulfoacetaldehyde to isethionate. The enzyme was partially purified and it apparently belonged to the family of short-chain alcohol dehydrogenases.
