ID   4.1.2.8
DE   indole-3-glycerol-phosphate lyase.
AN   (1S,2R)-1-C-(indol-3-yl)glycerol 3-phosphate D-glyceraldehyde-3-
AN   phosphate-lyase.
AN   indole-3-glycerolphosphate D-glyceraldehyde-3-phosphate-lyase.
AN   indole-3-glycerol phosphate lyase.
AN   indoleglycerolphosphate aldolase.
AN   indole glycerol phosphate hydrolase.
AN   indole synthase.
AN   tryptophan synthase alpha.
AN   TSA.
CA   (1S,2R)-1-C-(indol-3-yl)glycerol 3-phosphate = D-glyceraldehyde
CA   3-phosphate + indole.
CC   -!- Forms part of the defense mechanism against insects and microbial
CC       pathogens in the grass family, Gramineae, where it catalyzes one of
CC       the steps in the formation of the cyclic hydroxamic acids 2,4-
CC       dihydroxy-2H-1,4-benzoxazin-3(4H)-one (DIBOA) and 2,4-dihydroxy-7-
CC       methoxy-2H-1,4-benzoxazin-3(4H)-one (DIMBOA).
CC   -!- Resembles the alpha-subunit of EC 4.2.1.20 but, unlike tryptophan
CC       synthase, its activity is independent of the beta-subunit and free
CC       indole is released.
