In vitro mutagenesis analysis of the role of conserved residues of Muta1 transposase in transposition. (A) DNA binding assay using wild-type and mutant transposases. Diagram shows the structure of the DNA substrate. The unlabeled 165-bp DNA containing 20-bp flanking DNA and the full length Muta1 L-TIR is added in 100 (+) molar excess as competitor DNA. Binding products are resolved on a native polyacrylamide gel. (B) Cleavage assay using wild-type and mutant transposases. Diagram shows the structure of DNA substrates and predicted cleavage product. Reaction products are resolved on a native polyacrylamide gel. (C) End joining assay using wild-type and mutant transposases. Intact pUC19 plasmid is used as target DNA. Reaction products are resolved on a native agarose gel.
