Electron microscopy of the complexes of ribulose‐1,5‐bisphosphate carboxylase (Rubisco) and Rubisco subunit‐binding protein from pea leaves

Abstract

The structure of ribulose-1,5-bisphosphate carboxylase (Rubisco) subunit-binding protein and its interaction with pea leaf chloroplast Rubisco were studied by electron microscopy and image analysis. Electron-microscopic evidence for the association of Rubisco subunit-binding protein, consisting of 14 subunits arranged with 72 point group symmetry, and oligomeric (L8S8) Rubisco was obtained.
