tryptophan synthase
Enzyme Commission Number
EC 4.2.1.122
Product Overview
High-quality enzyme products.
Well-established quality management system.
Reaction
L-serine + indole = L-tryptophan + H2O
Systematic Name
L-serine hydro-lyase [adding indole, L-tryptophan-forming]
Function
Most mesophilic bacteria have a multimeric tryptophan synthase complex (EC 4.2.1.20) that forms L-tryptophan from L-serine and 1-C-(indol-3-yl)glycerol 3-phosphate via an indole intermediate. This intermediate, which is formed by the α subunits, is transferred in an internal tunnel to the β units, which convert it to tryptophan. In thermophilic organisms the high temperature enhances diffusion and causes the loss of indole. This enzyme, which does not combine with the α unit to form a complex, salvages the lost indole back to L-tryptophan. It has a much lower Km for indole than the β subunit of EC 4.2.1.20.
