Abstract:
Paracoccus denitrificans is a metabolically versatile alphaproteobacterium first isolated in 1910 by Martinus Beijerinck. Similarities between the aerobic respiratory chain and membrane composition of P. denitrificans and those of eukaryotic mitochondria have stimulated the use of P. denitrificans as a model for oxidative phosphorylation. The organism has also been used extensively as a model for studies of denitrification, cytochrome c biogenesis, lithotrophy using thiosulphate as a source of energy, methylotrophy, and carbon metabolism more broadly. Through the application of structural biology and modern genome-based approaches, work on P. denitrificans continues to make significant contributions across multiple areas of microbiology.
