Abstract

Neutron reflectometry has been used to study the self-assembly of a membrane protein, OmpF, onto a gold-coated silicon substrate from solution. OmpF associates into trimers and has been modified so that each trimer binds to the gold substrate through cysteine residues. Quantitative analysis of the data revealed that 12% of the surface was covered by the oriented protein with 27600 water molecules surrounding each trimer. © CSIRO 2005.
