Abstract
The monovalent cation (MVC) site of the tryptophan synthase from Salmonella typhimurium plays essential roles in catalysis and in the regulation of substrate channeling. In vitro, MVCs affect the equilibrium distribution of intermediates formed in the reaction of l-Ser with the α2β2 complex; the MVC-free, Cs+-bound, and NH4+-bound enzymes stabilize the α-aminoacrylate species, E(A-A), while Na+ binding stabilizes the l-Ser external aldimine...
