Nucleic acid-mimicking coordination polymer for label-free fluorescent activity assay of histone acetyltransferases†
Abstract
A novel and label-free fluorescence assay for histone acetyltransferase (HAT) activity was established via in situ generation of a nucleic acid-mimicking CoA–Au(I) coordination polymer (CP). Moreover, the potency of this assay for HAT-targeted drug discovery was proved by screening HAT inhibitors.
