The tilt angle of the retinal chromophore of bacteriophodopsin increases by approximately 4° upon isomerization in the M-state, as shown by accurate 2H-NMR measurements of methyl group bond orientations.
A new location for the hormone-binding site of corticosteroid binding globulin is propose based on experimental data, together with a sequence and structural alignment of the serpin family
A comparison of the structures of two cyanobacterial toxins yields insights into how they may inhibit protein phosphatase-1 and -2A and why microcystins but not motuporin may covalently modify their protein phosphatase targets.
Structural comparison identifies a similar basic fold for two enzymes which are involved in the phosphate-dependent formation or breakdown of oxygen-sugar linkages
A novel common fold observed in the structures of elongation factor G, DNA gyrase B and ribosomal protein S5 displays a rare topological feature suggesting the high probability of an evolutionary relationship
