In a system of purified components , binding of a DNA fragment ( 39 307 ) containing a Egr 1 binding site ( 5 ' CGCCCCCGC 3 ' from __NODE__ gene and a protein fragment containing a __NODE__ finger domain 1 4 from __NODE__ KTS protein is greater than binding of a DNA fragment ( 39 307 ) containing a Egr 1 binding site ( 5 ' CGCCCCCGC 3 ' from __NODE__ gene and a protein fragment containing a __NODE__ finger domain 1 4 from __NODE__ protein .
