Objective:To clone the whole encoding sequence of the uricase from Bacillus fastidious. Methods:According to the N-terminus amino sequence AERTMFYGKGDV from Edman degradation,bacterial uricases bearing similar N-terminus were sought in NCBI database by BLASTp;through multiple sequence alignment,two short conserved peptide fragments were found,one close to the N-terminus while the other close to the C-terminus. Using the known N-terminus and two conserved peptides,degenerated primers were designed for clonin...
