General annotation (Comments)

Function

The beta subunit is responsible for the synthesis of L-tryptophan from indole and L-serine. HAMAP MF_00133

Catalytic activity

L-serine + 1-C-(indol-3-yl)glycerol 3-phosphate = L-tryptophan + glyceraldehyde 3-phosphate + H2O. HAMAP MF_00133

Cofactor

Pyridoxal phosphate By similarity. HAMAP MF_00133

Pathway

Amino-acid biosynthesis; L-tryptophan biosynthesis; L-tryptophan from chorismate: step 5/5. HAMAP MF_00133

Subunit structure

Tetramer of two alpha and two beta chains By similarity.

Sequence similarities

Belongs to the TrpB family.
