Mechanisms of metal ion action in Tn10 transposition.

Abstract excerpt

Tn10/IS10 transposition involves assembly of a synaptic complex (or transpososome) in which two transposon ends are paired, followed by four distinct chemical steps at each transposon end. The chemical steps are dependent on the presence of a suitable divalent metal cation (Me(2+)). Transpososome assembly and structure are also affected by Me(2+). To gain further insight into the mechanisms of Me(2+) action in...
