p site造句

• IF2, bound to GTP, binds to the 30S P site.
• The " P site " is where the peptidyl tRNA is formed in the ribosome.
• The PS site is only needed to initiate elongation, not for the attachment of additional genomes.
• Macrolide antibiotics do so by binding reversibly to the P site on the 50S subunit of the bacterial ribosome.
• The ribosome has three active sites : the A site, the P site, and the E site.
• The tRNA on the P site ( without peptide ) moves to the E site and is then released.
• Independent grocers may pick up some of the A & P sites, said Chuck Gilmer, editor of the Shelby Report.
• The tRNA complex first binds to the A site, then moves to the P site, and is released at the E site.
• After associating with the 30S subunit, fMet-tRNA f binds to the IF2 then IF2 transfers the tRNA into the partial P site.
• Once translation initiation is complete, the first aminoacyl tRNA is located in the P / P site, ready for the elongation cycle described below.
• Near the end of July, things weren't looking too good for Napster, the most popular of these P-to-P sites.
• Erythromycin interferes with aminoacyl translocation, preventing the transfer of the tRNA bound at the A site of the rRNA complex to the P site of the rRNA complex.
• Then, a peptide bond forms between the amino acid of the tRNA in the A site and the amino acid of the charged tRNA in the P site.
• A third and rather novel approach that has been developed is creating transgenic mice with Cre-Recombinase, an enzyme that catalyzes recombination between two lox-P sites.
• By contrast, Harris Teeter entered the market in 1993 and tried to gain market share by buying some former A & P sites, mostly inside the Perimeter.
• The " A site " is the point of entry for the aminoacyl tRNA ( except for the first aminoacyl tRNA, which enters at the P site ).
• It's the largest city in the Southeast, and we have aggressively sought sites and got ourselves a market presence with old A & P sites ."
• The ribosome possesses three tRNA binding sites : the aminoacyl site ( A site ), the peptidyl site ( P site ), and the exit site ( E site ).
• Then by introducing an engineered viral vector containing the optogenetic actuator gene in between two lox-P sites, only the cells containing the Cre-Recombinase will express the microbial opsin.
• It has been suggested that after binding of the initiator tRNA to the P / I site, it is correctly positioned to the P site by binding of EF-P to the E site.
