RT   ammonia-lyase in Triticum aestivum.";
RL   (er) Plant Gene Register PGR96-102(1996).
CC   -!- FUNCTION: This is a key enzyme of plant metabolism catalyzing the first
CC       reaction in the biosynthesis from L-phenylalanine of a wide variety of
CC       natural products based on the phenylpropane skeleton.
CC       {ECO:0000250|UniProtKB:P24481}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-phenylalanine = (E)-cinnamate + NH4(+);
CC         Xref=Rhea:RHEA:21384, ChEBI:CHEBI:15669, ChEBI:CHEBI:28938,
