LDCC protein is also called lysine decarboxylase. As an enzyme that can catalyze the decarboxylation of lysine, it plays a key role in the utilization of lysine. This enzymatic activity enables LDCC to remove carboxyl groups from lysine, thereby generating cadaverine, a biogenic amine. LDCC Protein, E.coli (His) is the recombinant E. coli-derived LDCC protein, expressed by E. coli , with C-6*His labeled tag.
