Expression, purification, and characterization of a novel laccase from Setosphaeria turcica in Eschericha coli.

Laccases are multicopper oxidases (E.C. 1.10.3.2) that catalyze the oxidation of many phenolic compounds. In this study, a novel laccase, Stlac4, from Setosphaeria turcica was cloned and expressed in Escherichia coli by insertion into the pET-30a expression plasmid. The recombinant laccase was purified and visualized on SDS-PAGE as a single band with an… CONTINUE READING
