There is nothing wrong with crystal chandeliers in a barrel room, even in a relatively obscure chateau, until one realizes that it was financed by the ever-climbing prices of Bordeaux wines.
The pore-lining helices in this resting state feature alternative kinks near the conserved G121 instead of the G113 kinks observed in the crystal structure and the transmembrane barrel remains stable in extended molecular dynamics simulations.
Xylanases of the GH10 family are either endo-1,4-beta-xylanases or endo-1,3-beta-xylanases (EC 3.2.1.8), which have molecular masses ≥30 kDa and low isoelectric points [ 4], and their crystal structure displays a 8 barrel architecture [ 5].
The crystal structure shows the ubiquitous TIM α/β barrel fold.
These results confirmed our modeling predictions of a closed MscS channel featuring a TM3 barrel that largely resembles the crystal conformation though with more tightly packed peripheral helices.
As described in section 11.1.2, the HemN crystal structure comprises an incomplete 6 TIM barrel motif in addition to a unique C-terminal domain that is putatively involved in substrate binding.
After all, Agassi admitted in his autobiography to using crystal meth at the bottom of his barrel-scrapping journey.
Further, the ISME tip could clog with salt crystals from electrolyte originating from the reference barrel even after multiple rinses and >24 hours of soaking (Fig. 2).
Biotin synthase (BioB), thiamine pyrimidine biosynthetic enzyme ThiC, the hydrogenase biosynthetic enzyme HydE, and most recently PylB have crystal structures solved with complete 8 TIM barrels.
It occurs with galena, cerussite, and limonite in the oxidized zone of lead deposits, where it forms very brightly coloured, heavy, barrel-shaped crystals or globular masses.
The crystal structure of ChiA has revealed a TIM-barrel fold of the catalytic domain, an insertion between the B7 β-strand and A7 α-helix of the TIM-barrel, an FnIII domain at the N-terminus of the molecule and a hinge region that connects the latter to the catalytic domain.
