Function
Transposases bind to the ends of a transposon and catalyze its movement to another part of the genome by a cut-and-paste mechanism. Transposase contains a DDE motif in its active site enabling it to coordinate the binding of divalent metal ions. The metal ions affect transposase reactivity.
Mu transposase (MuA) is essential for integration, replication-transposition and excision of bacteriophage Mu DNA into multiple sites of bacterial genome. Mu transposition occurs within the transposome which is a protein-DNA complex which includes 4 subunits of MuA.
