WebThe relative spatial orientations of methylation sites and cleavage sites must play a major role in ordering protein secondary structure elements as well as subunit-subunit interactions along the DNA strand. AB - Methylation of nucleic acid bases is known to prevent the cleavage of DNA by restriction endonucleases. WebDSSP begins by identifying the intra-backbone hydrogen bonds of the protein using a purely electrostatic definition, assuming partial charges of −0.42 e and +0.20 e to the carbonyl oxygen and amide hydrogen respectively, their opposites assigned to the carbonyl carbon and amide nitrogen.
