Fig. 4From: Chlorella virus pyrimidine dimer glycosylase and Escherichia coli endonucleases IV and V have incision activity on 2,2,4-triamino-5(2H)-oxazoloneStructures of DNA lesions and possible recognition site of Nfi. a Structures of oxanine and the possible open- or closed-ring structure of Oz. Red circle indicates the common moiety that Nfi may recognize. b Structures of uracil, thymine and Gh. Red circle indicates the common moiety that Nfi may recognize. Blue circle indicates the moiety protruding from the six- or five-membered ring, and Nfi may disfavor these moietiesBack to article page
