Structural comparison of urease and a GroEL analog from Helicobacter pylori

J W Austin et al. J Bacteriol. 1992 Nov.

Abstract

Electron microscopy of purified protein preparations indicated that Helicobacter pylori urease consisted of circular particles that are 13 nm in diameter, some of which showed indications of threefold rotational symmetry. A GroEL analog of H. pylori (Hp60K) appeared as a disc-shaped molecule with a diameter similar to that of urease but possessed sevenfold rotational symmetry. In a side-view projection, Hp60K appeared as two or four discs stacked side by side.
