Fungal His-Tagged Nitrilase from Gibberella intermedia: Gene Cloning, Heterologous Expression and Biochemical Properties

Abstract

In the present study, a fungal nitrilase was cloned from the cDNA sequence of G. intermedia and successfully expressed in E. coli Rosetta-gami (DE3). The recombinant strain displayed good 3-cyanopyridine degradation efficiency and wide substrate spectrum. This fungal nitrilase might be a potential candidate for industrial applications in carboxylic acids production.
