Ambient STM and in situ AFM study of nitrite reductase proteins adsorbed on gold and graphite: influence of the substrate on protein interactions.

Abstract:

Trimeric Achromobacter cycloclastes Cu-containing nitrite reductase (CuNIR) proteins adsorbed on gold and graphite have been studied by ambient STM and in situ AFM. STM resolves them individually and in layers, distinguishing the sub-molecular individual units of the trimer. The Cu atoms are not visible to STM. STM shows that individual CuNIR denatures as it adsorbs on Au, although a deformed trimeric shape can be identified in some cases. CuNIR forms disordered layers on gold. On graphite, o...
