cis - Diamminedichloroplatinum(¥±) induces denaturation and conformational changes in pBR322 DNA




Abstract
E. coli LE392, transformed with CDDP-treated pBR322 DNA, was plated on ampicillin containing media. The number of colonies formed on ampicillin containing agar plate was reduced to undetectable level after trot the DNA with 13.3 ¥ìM CDDP. The CDDP- treated pBR322 DNA was susceptible to angle strand DNA specific Sl nuclease and it¢¥s migration pattern in agarose gel electrophoresis was changed. These results suggest, that CDDP adduction to pBR322 DNA resulted in denaturation of the double helix and changes in it¢¥s conformation which ultimately leads to the inactivation of the ampicillin resistant gene(Received November 25, 1990, Accepted December 22, 1990).
