It has been found that Ser His could cleave bovine serum albumin(BSA), with the most suitable pH around 6.0. The kinds of buffers have different influences on the cleavage activity. The phosphate buffer and BR buffer ...
Linear and supercoiled DNA were cleaved by HPLC purified seryl histidine dipeptide(SH). It was found that the DNA fragments produced by the reaction of SH and DNA could be ligated together by T 4 DNA ligase. This resu...
The effects of the amino, hydroxyl, imidazole and carboxyl groups of Ser His on DNA cleavage reaction were studied. It was found that the amino and hydroxyl groups were essential for the DNA cleavage activity of Ser H...
