Abstract excerpt
This work is aimed at understanding subunit assembly in the tryptophan synthase alpha 2 beta 2 complex and the importance of the internal aldimine between pyridoxal phosphate and lysine 87 of the beta 2 subunit of tryptophan synthase for subunit association. We utilize a mutant form of the beta 2 subunit that is unable to form the internal aldimine because lysine 87 is replaced by threonine (K87T). The K87T alpha...
