Nicking activity on pBR322 DNA of ribosome inactivating proteins from Phytolacca dioica L. leaves
{{output}}
Ribosome-inactivating proteins isolated from Phytolacca dioica L. leaves are rRNA-N-glycosidases, as well as adenine polynucleotide glycosylases. Here we report that some of them cleave supercoiled pBR322 dsDNA, generating relaxed and linear molecules. PD-L1, ... ...
