Fig. 5. Schematic stereo view of the superimposed monomer
structures of the tryptophan synthase  from P.
furiosus and S. typhimurium. Blue and red lines represent the
coordinates of Pf and St (1BKS),
respectively. Drawings were prepared using MOLSCRIPT.
Residual numbers are shown with an increase of 10 for the Pf
. An arrow
indicates the most different part between the proteins around
position 60 of Pf .
