- * Transposases, Mutator family, signature *
- *******************************************
-
- Autonomous mobile genetic elements such as transposon or insertion sequences
- (IS) encode an enzyme, called transposase, which is required for the excision
- and insertion of the mobile element. On the basis of sequence similarities,
- transposases can be grouped into various families. One of these families has
- been shown [1,2,3] to consist of transposases from the following elements:
-
- - Mutator from Maize.
- - Is1201 from Lactobacillus helveticus.
- - Is905 from Lactococcus lactis.
- - Is1081 from Mycobacterium bovis.
- - Is6120 from Mycobacterium smegmatis.
- - Is406 from Pseudomonas cepacia.
- - IsRm3 from Rhizobium meliloti.
- - Is256 from Staphylococcus aureus.
- - IsT2 from Thiobacillus ferrooxidans.
-
- The maize Mutator transposase (MudrA) is a protein of 823 amino acids; the
- bacterial transposases are proteins of 300 to 420 amino acids. These proteins
- contain a conserved domain of about 130 residues. We have derived a signature
- pattern from the most conserved part of this domain.
-
- -Consensus pattern: D-x(3)-G-[LIVMF]-x(6)-[STAV]-[LIVMFYW]-[PT]-x-[STAV]-x(2)-
- [QR]-x-C-x(2)-H
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
