Characterization of an operon encoding an NADP-reducing hydrogenase in Desulfovibrio fructosovorans.

abstract：:Two novel insertion sequences, IS1312 and IS1313, were found in pTiBo542, the Ti plasmid of Agrobacterium tumefaciens strains Bo542 and A281. Nucleotide sequencing and Southern hybridization revealed that IS1312 and IS1313 are homologous to Rhizobium meliloti ISRm1 and ISRm2, respectively. IS1312, ISRm1, and another A...
