These operons are: trpEDCBA, which encodes the enzymes committed to L-tryptophan biosynthesis; aroH,which encodes one of the isozymes for the first step in aromatic amino acid biosynthesis; and trpR, which encodes the trp aporepressor protein (Joachimiak et al. 1983; Somerville 1983)....

Terms to be familiar with before you start to solve the test: tryptophan, transcription unit, operon, trp repressor, corepressor, operator, promoter, palindrome, initiation, elongation, and termination of transcription, open reading frame, coupled transcription/translation, chromosome–polysome complex. ...
Several DNA-binding proteins show the affinities for their specific DNA sites that positively depend on the length of DNA harboring the sites, i. e. antenna effect. DNA looping can cause the effect for proteins with two or more DNA binding sites, i. e. the looping mechanism. One-dimensional...
Enhanced operator binding by Trp superrepressors of Escherichia coli The trp repressor of Escherichia coli binds to the operators of three operons concerned with tryptophan biosynthesis and regulates their expression. trp su... BK Hurlburt,C Yanofsky - 《Journal of Biological Chemistry》 被引量: 74...
T241 were cloned and assembled along with AC operon from S. marcescens H30 into pET28a vector, to generate the plasmids pET-budRAB-bdh1, pET-budRAB-bdh2, pET-budRAB-bdh3 and pET-budRAB-gdh. All of the plasmids harbored the AC operon (budRAB), which is used to produce acetoin ...
Oxidizes proline to glutamate for use as a carbon and nitrogen source and also function as a transcriptional repressor of the put operon.

The mechanism of the interaction of uncharged tRNA and stringent factor with the ribosomes during the in vitro synthesis of guanosine polypnophates (pppGpp and ppGpp) was studied. 70S ribosomes lacking proteins L7 and L12 were able to bind radioactive stringent factor but not EF-Tu or EF-...
Magnesium protoporphyrin IX O-methyltransferase (ChlM) catalyzes transfer of the methyl group from S-adenosylmethionine to the carboxyl group of the C13 propionate side chain of magnesium protoporphyrin IX. This reaction is the second committed step in chlorophyll biosynthesis from protoporphyrin IX. ...
led to proposition that the transporter contains the involved sensory domain of the s ystem40,42. More recently, the binding of AMP LL-37 to the ECD of VraG (a BceAB homologous transporter) was described in B. subtilis37. Similar operon structures have been reported for other BceAB-...
