TnsA-like heteromeric transposase endonuclease subunit The transposase of transposon Tn7 contains multiple subunit. Members of this family are largely restricted to the Actinobacteria, resemble the endonuclease subunit TsnA of the multimeric transposase of Tn7 and its relatives, and occur in genomic neighborhoods that suggest a similar role in transposition.
