title: Effects of sample preparation conditions on biomolecular solid-state NMR lineshapes.
abstract: Sample preparation conditions with the 46 kDa enzyme complex of 5-enolpyruvyl-shikimate-3-phosphate (EPSP) synthase, shikimate-3-phosphate (S3P) and glyphosate (GLP) have been examined in an attempt to reduce linewidths in solid-state NMR spectra. The linewidths of 31P resonances associated with enzyme bound S3P and GLP in the lyophilized ternary complex have been reduced to 150 +/- 12 Hz and 125 +/- 7 Hz respectively, by a variety of methods involving additives and freezing techniques.
