PCNA IS NORMALLY A TRIMER BUT NEM MODIFICATION DISRUPTS THE TRIMER AND CAUSES PCNA TO RUN AS A MONOMER ON GEL FILTRATION THIS SUMO-PCNA MONOMER CRYSTALLIZES BY REFORMING THE PCNA:PCNA PROTOMER BUT WITH A RIGHT HANDED HELICAL SCREW COMPOSED OF 4 SUBUNITS THE ASU HAS 2 AND THE UNIT CELL CONTAINS ONE TURN OF THIS HELICAL SCREW WITH 4 PROTOMERS
