Tryptophan synthase Q114A mutant in complex with N-(4'-trifluoromethoxybenzenesulfonyl)-2-amino-1-ethylphosphate (F9F) at the enzyme alpha-site, cesium ion at the metal coordination site, and 2-aminophenol quinonoid at the enzyme beta site

Marker proteins were used for column calibration: ferritin (440 kDa), aldolase (158 kDa), conalbumin (75 kDa), and lactalbumin (14 kDa). The effluent was monitored by absorbance at 280nm and the protein sample from the peak fraction was loaded in a 15% SDS-PAGE gel. Tryptophan synthase is a tetrameter composed of two alpha-chains and two beta-chains (Alpha2-Beta2).
