We show here that the Enterobacterium Salmonella typhimurium LT2 has the capacity to grow anaerobically on l(+)- or d(-)-tartrate as sole carbon and energy source. Growth on these substrates was Na+-dependent and involved the l(+)- or d(-)-tartrate-inducible expression of oxaloacetate decarboxylase. The induced decarboxylase was closely related to the oxaloacetate decarboxylase Na+ pump of Klebsiella pneumoniae as shown by the sensitivity towards avidin, the location in the cytoplasmic membrane, activation by Na+ ions, and Western blot analysis with antiserum raised against the K. pneumoniae oxaloacetate decarboxylase. Participation of an oxaloacetate decarboxylase Na+ pump in l(+)-tartrate degradation by S. typhimurium is in accord with results from DNA analyses. The deduced protein sequence of the open reading frame identified upstream of the recently sequenced oxaloacetate decarboxylase genes is clearly homologous with the β-subunit of l-tartrate dehydratase from Escherichia coli. Southern blot analysis with S. typhimurium chromosomal DNA indicated the presence of probably more than one gene for oxaloacetate decarboxylase.
