Crystal structure of the Mos1 mariner paired end complex with Mn
Template:ABSTRACT PUBMED 19766564
Function
[MOS1T_DROMA] Mediates transposition of transposon Mos1 by a 'cut and paste' mechanism. Transposases are sequence-specific nucleases and strand transferases that catalyze transposition through an ordered series of events: sequence-specific binding of transposase to the terminal inverted repeats (IR) present at each end of the transposon, pairing of the transposon IRs in a paired-end complex (PEC), cleavage of one or both DNA strands at each transposon end, capture of target DNA, and strand transfer to insert the transposon at a new site.
About this Structure
3hot is a 8 chain structure with sequence from Drosophila mauritiana. Full crystallographic information is available from OCA.
