SMUG1 is a single-strand selective monofunctional uracil DNA glycosylase that cleaves uracil from the sugar phosphate backbone of DNA. SMUG1 has the highest preference for uracil in single strand DNA, followed by A:U and then G:U pairs in double strand DNA (Haushalter et al. 1999, Masaoka et al. 2003).
