7LY8
The internal aldimine form of the wild-type salmonella typhimurium tryptophan synthase in complex with two molecules of n-(4'-trifluoromethoxybenzoyl)-2-amino-1-ethylphosphate (f6f) inhibitor at the enzyme alpha-site, a single f6f molecule at the enzyme beta-site, and sodium ion at the metal coordination site at 1.55 angstrom resolution. one of the beta-q114 rotamer conformations allows a hydrogen bond to form with the plp oxygen at the position 3 in the ring
