X-RAY DIFFRACTION	?	?	PRIOR TO CRYSTALLISATION THE PCNA1-PCNA2-PCNA3 COMPLEX WAS MIXED WITH FEN1 AT AN EQUIMOLAR RATIO AND INCUBATED FOR 20 MIN AT 294 K. PCNA1-PCNA2-FEN1 CO-CRYSTALS WERE GROWN BY THE VAPOUR DIFFUSION METHOD IN HANGING DROPS. PCNA3 WAS NOT PRESENT IN THE CRYSTAL LATTICE. DROPS WERE PREPARED BY MIXING 100 MM PROTEIN COMPLEX IN 20 MM TRIS-HCL PH 8.0, 200 MM NACL, 5 MM MGCL2, 2 MM DTT BUFFER SOLUTION WITH EQUAL VOLUMES OF 0.1M ACETATE PH 4.8, 8% PEG 8,000, 220 MM ZNOAC2 AND 30 MM GLYCYL-GLYCYL-GLYCINE.
