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...

the His operon. This operon has a distinct block of the leader sequence, called block 1: Met-Thr-Arg-Val-Gln-Phe-Lys-His-His-His-His-His-His-His-Pro-Asp...

The Histidine operon leader is an RNA element found in the bacterial histidine operon. At least 6 amino acid operons are known to be regulated by attenuation...

include the histidine (his) and tryptophan (trp) biosynthetic operons. The term "attenuation" was introduced to describe the his operon. While it is typically...

California, Davis. He became well known for his early studies on the structure and regulation of the his operon of Salmonella, and went on to investigate...

the adjacent promoter to start transcription of the lac operon, increasing the rate of lac operon transcription. With a high glucose concentration, the...

synthesis". Monod and Jacob became famous for their work on the E. coli lac operon, which encodes proteins necessary for the transport and breakdown of the...

metabolize the second sugar. Monod later put aside his work on diauxic growth and focused on the lac operon model of gene expression, which led to a Nobel...

of the operon, called the operator region, and represses transcription of the operon; when the repressor is inactive transcription of the operon can occur...

the his and the Shi-A operon of the bacterium. The nif regulon comprises 7 operons: nifRLA, nifJ, nifHDK, nifEN, nifUSVM, nifWF, nifBQ. nifRLA operon: The...

an operon is a stretch of DNA that is transcribed to create a contiguous segment of RNA, but contains more than one cistron / gene. The operon is said...

regulate the expression of the anthrax toxin genes. pXO2 encodes a five-gene operon (capBCADE) which synthesizes a poly-γ-D-glutamic acid (polyglutamate) capsule...

neighborhood of the his operon. Shen examined 7 different nif genes and proved that they were all mapped in a single cluster in the his region, without the...

thus alters its binding ability for the regulatory region of a gene or operon. Charles Yanofsky was born on April 17, 1925, in New York. He was one of...

initiation codons are those of lacI (GUG) and lacA (UUG) in the E. coli lac operon. Two more recent studies have independently shown that 17 or more non-AUG...

are located in the same operon as their cognate histidine kinase; lateral gene transfers are more likely to preserve operon structure than gene duplications...
