Function
function
The beta subunit is responsible for the synthesis of L-tryptophan from indole and L-serine.
Catalytic activity
- (1S,2R)-1-C-(indol-3-yl)glycerol 3-phosphate + L-serine = D-glyceraldehyde 3-phosphate + H2O + L-tryptophan
Cofactor
Pathway
Amino-acid biosynthesis; L-tryptophan biosynthesis; L-tryptophan from chorismate: step 5/5.
