Engineering Galactose Oxidase to Increase Expression Level in E. coli, Enhance Thermostability and Introduce Novel Activities [PDF]

open access: yes, 2003
For the first time, we functionally expressed the fungal glycosylated copper-containing enzyme, galactose oxidase, in Escherichia coli. The generation of fully functional GOase confirms that the formation of the unusual thioether bond is an auto ...
