A RuBisCO-mediated carbon metabolic pathway in methanogenic archaea
Abstract
Although not photosynthetic, some archaea possess RuBisCO, one of the enzymes characteristic of the photosynthetic Calvin-Benson cycle, but apparently lack another one, phosphoribulokinase (PRK). Here the authors describe a carbon metabolic pathway in methanogenic archaea, involving RuBisCO and PRK.
