Immobilization of engineered arginase on gold-carbon nanotubes

Chem Commun (Camb). 2012 Aug 11;48(62):7693-5. doi: 10.1039/c2cc32863a.

Abstract

It is demonstrated that engineered arginase with a single protruded site of cysteine deliberately placed away from its active centre by site-directed mutagenesis can facilitate its attachment on a gold-nanoparticle surface with atomic precision, resulting in no apparent loss in enzymatic activity.
