- In genetics, an
operon is a
functioning unit of DNA
containing a
cluster of
genes under the
control of a
single promoter. The
genes are
transcribed together...
- The
lactose operon (lac
operon) is an
operon required for the
transport and
metabolism of
lactose in E. coli and many
other enteric bacteria. Although...
- trp
operon is a
group of
genes that are
transcribed together,
encoding the
enzymes that
produce the
amino acid
tryptophan in bacteria. The trp
operon was...
- In genetics,
attenuation is a
regulatory mechanism for some
bacterial operons that
results in
premature termination of transcription. The
canonical example...
-
dimeric protein that
regulates transcription of the 5
genes in the
tryptophan operon. When the
amino acid
tryptophan is
plentiful in the cell, it
binds to the...
- The L-arabinose
operon, also
called the ara or
araBAD operon, is an
operon required for the
breakdown of the five-carbon
sugar L-arabinose in Escherichia...
- and the
silencer region to come in
proximity of each other. The
lacZYA operon houses genes encoding proteins needed for
lactose breakdown. The lacI gene...
- The
threonine operon leader is an RNA element.
Threonine is one of at
least 6
amino acid
operons are
known to be
regulated by attenuation. In each a leader...
-
carried out by a gene
cluster known as the bile acid-inducible (bai)
operon. The bai
operon encodes the
genes baiB, baiCD, baiE, baiA, baiF, baiG, baiH, and...
- The
Tryptophan operon leader is an RNA
element found at the 5′ of some
bacterial tryptophan operons. The
leader sequence can form two
different structures...
