Ribulose 1,5-bisphosphate
Ribulose 1,5-bisphosphate (RUBP) is a vital photosynthetic intermediate and substrate. Ribulose 1,5-bisphosphate acts as both product and substrate for Thermococcus kodakarensis KOD1 R15Pi. Ribulose 1,5-bisphosphate tightly binds to inactive RuBP carboxylase sites in plant leaves.Ribulose 1,5-bisphosphate serves as the key substrate for CO2 fixation in photosynthesis. Ribulose 1,5-bisphosphate supports carboxylation and regeneration processes in photosynthesis. Ribulose 1,5-bisphosphate determines the dynamic transition temperature of photosynthetic control. Ribulose 1,5-bisphosphate can be used for photosynthesis and enzyme mechanism research.

Biological Activity
Ribulose 1,5-bisphosphate (RuBP) binds to inactive RuBP carboxylase sites in intact spinach leaves with an in vivo dissociation rate constant of 1.54 × 10-3 s-1[2].
Ribulose 1,5-bisphosphate binds to inactive RuBP carboxylase sites in intact sunflower leaves and declines to match inactive site levels within 60 s of darkening[2].
Ribulose 1,5-bisphosphate supports carboxylation and regeneration that decline seasonally in Shiraz grapevines, with a dynamically shifting transition temperature[3].
