Table 2 Activities measured for the conversion of glucose to 3-PGA in nanostructure-multienzyme complexes with R. rubrum form II (FII) RubisCO

From: Synthetic CO2-fixation enzyme cascades immobilized on self-assembled nanostructures that enhance CO2/O2 selectivity of RubisCO

Enzyme cascade Combined activitya (μmoles/min-mg) % Activity ret.b
Unbound FII and glucose pathwayc 0.259 100
FII and glucose pathwayc in nanotube A 0.100 39
FII and glucose pathwayc in nanotube B 0.110 42
FII and glucose pathwayc in nanofiber C 0.115 44
  1. aCalculated from stable 14CO2 fixed
  2. bActivities retained are presented relative to an unbound enzyme mixture comprising all enzymes. Activity numbers are from one of the two assays conducted with independently prepared and assayed nanostructure complexes, which gave similar results
  3. cGlucose pathway comprises all enzymes that constitute pathway 2
