UNG E. Coli Recombinant produced in E. Coli is a single, non-glycosylated polypeptide chain containing 252 amino acids (1-229 a.a) and having a molecular mass of 28.1kDa. UNG is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. UNG is a member of the Uracil-DNA glycosylase family. One of his functions is to prevent mutagenesis by eliminating uracil from DNA molecules by cleaving the N-glycosylic bond and initiating the base-excision repair (BER) pathway. Uracil bases are formed as a result of cytosine deamination or misincorporation of dUMP residues. After a mutation is formed, the mutagenic threat of uracil propagates through any subsequent DNA replication steps. Among the diseases associated with UNG are: congenital rubella, and immunodeficiency with hyper igm type 4.
