Testing commercial protein crystallography sample mounting loops for movement in a cold-stream

Autor: Frank J. Rotella, R. W. Alkire, N. E. C. Duke

Publikováno v: Journal of Applied Crystallography. 46:525-536

The purpose of this study was to determine the relative stiffness of the more common sample mounting loops used in protein crystallography experiments and to see if they were moving under the influence of the nitrogen cold-stream gas. The `stress tes

Putative outer membrane c-type cytochromes have been implicated in metal ion reducing properties of Geobacter sulfurreducens. OmcF (GSU2432), OmcB (GSU2731), and OmcC (GSU2737) are three such proteins that have predicted lipid anchors. OmcF is a mono

Is your cold-stream working for you or against you? An in-depth look at temperature and sample motion

Autor: N. E. C. Duke, Frank J. Rotella, R. W. Alkire

Publikováno v: Journal of Applied Crystallography. 41:1122-1133

It is normally assumed that a commercial gaseous nitrogen cold-stream provides a sample environment near 100 K and that the force of the cold-stream does not induce movement in the sample. As might be expected, the reality is much more complex. Here,
