Tryptophan repressor (or trp repressor) is a
transcription factor involved in
controlling amino acid metabolism. It has been best
studied in Escherichia...

Tryptophan synthase or
tryptophan synthetase is an
enzyme (EC 4.2.1.20) that
catalyzes the
final two
steps in the
biosynthesis of
tryptophan. It is commonly...
- In enzymology, a
tryptophan transaminase (EC 2.6.1.27) is an
enzyme that
catalyzes the
chemical reaction L-

- In enzymology,
tryptophan 2,3-dioxygenase (EC 1.13.11.11) is a heme
enzyme that
catalyzes the

- bacteria. The
operon is
regulated so that, when
tryptophan is
present in the environment, the
genes for
tryptophan synthesis are repressed. The trp
operon contains...
