Genomic analysis reveals chromosome conservation and absent hydrogenase genes in Cupriavidus necator N-1, highlighting divergence from related bioplastic-producing strains.
Here we announce the complete genome sequence of the copper-resistant bacterium Cupriavidus necator N-1, the type strain of the genus Cupriavidus. The genome consists of two chromosomes and two circular plasmids. Based on genome comparison, the chromosomes of C. necator N-1 share a high degree of similarity with the two chromosomal replicons of the bioplastic-producing hydrogen bacterium Ralstonia eutropha H16. The two strains differ in their plasmids and the presence of hydrogenase genes, which are absent in strain N-1.
Poehlein et al. (2011) studied this question.
