Because of the robustness of their barrel structures, βMPs have great potential as nanosensors for single-molecule detection.
Altogether, the high pressure NMR experiment has revealed a variety of fluctuating conformers of β-lactoglobulin, notably N, N′, I1, I2 and the totally unfolded conformer U. Fluctuation of N to I1 and I2 conformers with open barrel structures could be a common design of lipocalin family proteins which bind various hydrophobic compounds in its barrel structure.
All TIMs belong to the family of α/β barrel structures; the center of the barrel is formed by 8 β-strands which are surrounded by 8 α-helices; the helices and the strands are joined by loops.
Position and length of some helices, strands and loops of the TIM barrel structures are changed, which contributes, to a certain degree, to the distinctly different shaped 8-barrels, thus affecting the catalytic environment of these enzymes.
The TIM barrels can vary from closed barrel structures to open, splayed barrels.
The tags appear as globular densities consistent with the β barrel structures of GFP and BFP.
