چکیده انگلیسی
This report describes a novel carboxyl pendant containing adenylated polymeric template, its metalation with Zn (II), and manifestation of catalytic activity for the hydrolysis of model phosphodiester, bis(p-nitrophenyl) phosphate (bNPP), and plasmid cleavage. Observation of a bell-shaped pH-Kobs profile suggested influence of pH variation over hydrolysis rate. This metalated polymer also afforded facile relaxation of pBR322 supercoiled DNA, with an interesting reusability feature intricately associated with heterogeneous catalysis.
Phosphate ester hydrolysis and plasmid relaxation by metalated modified adenine polymer containing carboxyl group appendages is reported.Figure optionsDownload as PowerPoint slide
