abstract：:The methyltransferase, M.EcoKI, recognizes the DNA sequence 5'-AACNNNNNNGTGC-3' and methylates adenine at the underlined positions. DNA methylation has been shown by crystallography to occur via a base flipping mechanism and is believed to be a general mechanism for all methyltransferases. If no structure is available...

abstract：:We had shown previously (3) that the E. coli argE gene could be turned-on by an IS3 element inserted in orientation II near the 5' end of the gene. Here we show that this effect is due to the presence of an outward promoter located on IS3. The exact site of insertion of IS3 was determined by DNA sequencing. Using the ...
