Oxidative pentose phosphate pathway (red) carrying carbon into the Calvin-Benson cycle (grey). 3PGA, 3-phosphoglycerate; 6PG, 6-phosphogluconate; 6PGL, 6-phosphogluconolactone; ATP, adenosine ...

None of the autotrophic archaea seems to use the Calvin cycle for CO 2 fixation ... Recently a highly conserved, heat-stabile and bifunctional fructose 1,6-bisphosphate aldolase–phosphatase ...
