GUS tetramers

Hi folks,

beta-glucoronidase (GUS to friends) is a handy and frequently used
reporter for protein fusions.  I gather that the active enzyme is in the
form of a tetramer.  Despite the numerous papers I've read in which this
reporter was used I am unable to track down information on how GUS
tetramers are formed ie which part(s) of protein is required for tetramer
formation.  Any comments or references are welcome.

Thanks in advance,

Michael Goodin
