✦ Synopsis

The structure of spinach ribulose 1,5-bisphosphate carboxylase/oxygenase (EC 4.1.1.39) has been investigated by tilted-view electron microscopy of negatively stained monolayer crystals and image processing. The structure determined consists of a cylinder of octagonal cross-section with a large central hole. Based on this and other available evidence a model for the arrangement of the large and small subunits is suggested with the eight small subunits arranged equatorially around the core of eight large subunits.

Ribulose 1,5-bisphosphate carboxylase (EC.4.1.1.39) has been obtained from Nicotiana tabacum leaf homogenates with specific activites from 0.5 to 0.8 µmol CO2 fixed (mg protein min)(-1). These activities are reconciled with much lower, previously reported activities. The results suggest that if the
