Complexes of Rhodobacter sphaeroides and Rhodobacter capsulatus
Photosynthetic bacteria offer excellent experimental opportunities to explore both the structure and function of the ubiquinol-cytochrome c oxidoreductase (bcl complex). In both Rhodobacter sphaeroides and Rhodobaeter capsulatus, the bCl complex functions in both the aerobic respiratory chain and as an essential component of the photosynthetic electron transport chain. Because the bc~ complex i...

15 صفحه اولPolyhydroxyalkanoate production in Rhodobacter capsulatus: genes, mutants, expression, and physiology.
Like many other prokaryotes, the photosynthetic bacterium Rhodobacter capsulatus produces high levels of polyhydroxyalkanoates (PHAs) when a suitable carbon source is available. The three genes that are traditionally considered to be necessary in the PHA biosynthetic pathway, phaA (beta-ketothiolase), phaB (acetoacetylcoenzyme A reductase), and phaC (PHA synthase), were cloned from Rhodobacter ...
