termination factors造句

• The most extensively studied transcriptional termination factor is the Rho protein of " E . coli ".
• The yeast prion PSI is generated by a conformational change of a translation termination factor, which is then inherited by daughter cells.
• Other termination factors discovered in " E . coli " include Tau and nusA . Rho-dependent terminators were first discovered in bacteriophage genomes.
• NusG binds to termination factor Rho and to RNAP . It stimulates the rate of transcription elongation and is required for the activity of certain Rho-dependent terminators.
• Eukaryotic termination factors bind to the termination signal region and disturb RNA polymerase II as it moves by, causing it to fall off the DNA strand within the next 300 base pairs.
• "' The alpha and beta ( or A and B ) subunits "'are found in the F1, V1, and A1 complexes of F-, V-and A-ATPases, respectively, as well as flagellar ATPase and the termination factor Rho.
• This domain does not contact RNA, and instead, it recognizes 15 residues sequences that are a part of the PABP interaction motif ( PAM-2 ) found on such proteins as eukaryotic translation termination factor ( eRF3 ) and PABP interacting proteins 1 and 2 ( PAIP 1, PAIP2 ).
