Abstract
Using electron microscopy, the spatial structure of glutamine synthetase from pea leaf chloroplasts was studied. The enzyme was shown to consist of eight elongated subunits, which are arranged with a point of 42 symmetry at the vertices of two squares. These squares are twisted about a 4-fold axis at 40 degrees relative to each other.
