Crystal structure of metagenome-derived LC9-RNase H1 with atypical DEDN active site motif.

abstract：:Properties of Klebsiella pneumoniae respiratory chain enzymes catalyzing NADH oxidation have been studied. Using constructed K. pneumoniae mutant strains, it was shown that three enzymes belonging to different families of NADH:quinone oxidoreductases operate in this bacterium. The NDH-2-type enzyme is not coupled with...
