Screening and Characterization of Bacterial Laccase and Asparaginase

Abstract

Laccases are oxidase which have multiple copper ions and is one of the lignin-degrading enzymes that have been studied since 18th century [1]. It comes under the group of blue oxidases which helps to catalyze the oxidation of phenols, aromatic amines, polyphenols and different non-phenolic substrates by using molecular oxygen from the atmosphere as an electron acceptor. [2]Laccases, when it is enzymatically active can be either in dimer or timer form. The name Laccase is derived from a Chinese lacquer tree from which this enzyme was first studied, by Gabriel Bertrandin in 1894.
