Transposon Tn7 transposition protein TnsA

Gene

tnsA

Organism
Escherichia coli
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Required for Tn7 transposition. Forms the transposase, together with TnsB. TnsA executes the 5'-DNA strand breakage reaction. TnsABC and TnsD promote high-frequency insertion of Tn7 into a specific target site known as ATT-Tn7 whereas TnsABC and TnsD promote low-frequency insertion into many different sites.2 Publications
