The bacterial SOS response promotes the expression of the transposase encoded by ISCR mobile genetic elements

Claire Lallement, Thomas Jové, Cécile Pasternak…·Marie-Cécile Ploy

The paper shows that the bacterial SOS response, via LexA, regulates ISCR transposase expression, linking antibiotic exposure to increased transposon mobility.

Dual regulatory role of IS91-encoded Orf121 in IS91 transposition

Aurélien Fauconnier, Sandra Da Re, Margaux Gaschet…·Cécile Pasternak

The paper investigates the dual role of IS91-encoded Orf121 in IS91 transposition, showing it negatively regulates transposition while supporting tnpA expression.
