Abstract
The 4 kb DNA region located immediately upstream of the Rhizobium legu minosarum by. viciae UPM791 hydrogen structural genes was sequenced an d found to encode a chemoreceptor of the methyl-accepting type, the fi rst to be described in a rhizobial symbiotic plasmid. Two additional o pen reading frames were found. Their protein products showed sequence homology to dehydrogenases and isomerases involved in the metabolism o f aromatic compounds. Mutant analysis showed that this region is not r equired for hydrogenase activity.
