This transposase is essential for integration, replication-transposition and excision of Bacteriophage Mu DNA. Transposition requires transposase and a transposition enhancer, and the DNA can be transposed into multiple sites in bacterial genomes.
The crystal structure of the core domain of Mu transposase, MuA, has been determined. The first of two subdomains contains the active site and, despite very limited sequence homology, exhibits a striking similarity to the core domain of Human immunodeficiency virus 1 integrase. The enzymatic activity of MuA is known to be activated by formation of a DNA-bound tetramer of the protein [PUBMED:7628012].
More information about these proteins can be found at Protein of the Month: Transposase [PUBMED:].

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the DDE_2 domain has been found. There are 5 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
