The structure of the tryptophan synthaseb2 subunit (Pfb2 ) from the hyperthermophile,Pyrococcus furiosus,was deter-mined by X-ray crystallographic analysis at 2.2 A˚ resolu-tion, and its stability was examined byDSC. This is the first report of the X-ray structure of the tryptophan synthaseb2 subunit alone, although the structure of the tryptophan synthase a2b2 complex fromSalmonella typhimuriumhas already been reported. The structure ofPfb2was essentially similartothatoftheb2 subunit (Stb2)inthea2b2complex from S. typhimurium....
