2.8.1.15	in complex with TtuB sulfur carrier protein, to 2.5 A resolution	739824	
2.8.1.15	sitting drop vapor diffusion method at 208C, using 1 microl of sample solution mixed with an equal volume of reservoir solution, composed of 100 mM Bicine–NaOH buffer (pH 9.0) containing 200 mM NaCl, 12% (w/v) polyethylene glycol(PEG) 3350, and 0–10% (v/v) N,N-dimethylformamide. The native crystal belongs to the space group P43212, with unit cell parameters of a 5 b 5 70.1 Angstrom and c 5 128.6 Angstrom	739609	
2.8.1.15	structure of the TtuA-TtuB complex, at a resolution of 2.5 A, showing the S transfer of TtuB to tRNA using its C-terminal thiocarboxylate group. The active site of TtuA is connected to the outside by two channels, one occupied by TtuB and the other used for tRNA binding	741346	
2.8.1.15	to 2.1 A resolution. TtuA forms a homodimer, and each subunit contains a catalytic domain and unique N- and C-terminal zinc fingers. Three conserved cysteine residues are clustered in the putative catalytic site	741379	
2.8.1.15	vapour-diffusion method at 293 K under anaerobic conditions, 2-thioribothymidinesynthetic complex TtuA–TtuB	737395
