Abstract
The regulation of the amount of carbon fixed by photosynthetic organisms is ultimately controlled by the kinetic parameters of ribulose-1,5-P2 carboxylase (Rubisco). The enzyme dictates the flow of ribulose-P2 through either photosynthetic carbon reduction leading to a net gain of organic carbon, or photorespiration, the loss of fixed carbon through oxygenation. Both of these activities, carboxylation or oxygenation of ribulose-P2, are catalysed at the same active site within the large (L) subunit of Rubisco. This bifunctionality of the enzyme is quite unique especially as there is apparently no requirement for transition metal prosthetic groups e.g. Cu or Fe, normally associated with oxygenation reactions. Clearly then to understand how the enzyme partitions the bisphosphate substrate between the opposing processes of carbon fixation and oxygenation requires detailed investigation of the two activities at the molecular level, particularly the nature of the groups that compose the active site.
