Moreover , ZK161422 , but not ZK157202 , showed preference for gene activation from a promoter carrying a VD response element with a palindromic arrangement of two hexameric receptor binding sites spaced by 9 nucleotides ( IP9 ) rather than for activation from a response element formed by a direct repeat spaced by 3 nucleotides ( DR3 ) .
