Type I topoisomerase protein bound to DNA
Type I topoisomerase bound to DNA. Molecular model showing a type I topoisomerase molecule (blue) bound to a strand of DNA (deoxyribonucleic acid,yellow and red). The topoisomerase enzymes assist in uncoiling DNA. DNA is usually stored in a supercoiled form,which must be unravelled before it can be replicated or translated into proteins. Type I topoisomerase changes the linkage in multiples of one,while Type II changes the linkages in steps of two
