X-ray fluorescence (XRF) has been used to determine in vivo the percutaneous absorption of 5-iodouracil (5IU) in dimethyl sulfoxide (DMSO) on female Sprague-Dawley rats. An average absorption rate constant of 122 +/- 34 micrograms/cm2-hr was obtained from the XRF measurements

DNA methyltransferases flip their target base out of the DNA helix. Here, we have investigated base flipping by wild-type EcoRV DNA methyltransferase (M.EcoRV) and five M.EcoRV variants (D193A, Y196A, S229A, W231R and Y258A). These variants bind to DNA and S-adenosylmethionine
