  release factor
Substitutions of the Glutamine Residue in the ubiquitous GGQ tripeptide in human eRF1 do not entirely abolish the release factor
      
Identification of eRF3b, a Human Polypeptide Chain Release Factor with eRF3 Activity in vitroand in vivo
      
We have cloned the cDNA encoding the human eRF3b, purified the eRF3b expressed in Escherichia coli, and found that the protein is active in vitroas a potent stimulator of the release factor activity of human eRFl.
      
Since 18S rRNA modification did not depend on whether the U4 photoreactive group was in the sense or stop codon, it was assumed that polypeptide chain release factor 1 directly recognizes the trinucleotide of a stop codon located in the A site.
      
Release factor 3 (RF3) catalyzes the release of termination factors 1 or 2 (RF1 or RF2) from the ribosomal complex after completion of protein synthesis and peptidyl-tRNA hydrolysis.

25Hz long track circuit is the longest track circuit in our country today. Its transmitted end uses the 25Hz Ferro-magnetic frequency divider, which was introduced in the Vol.8 No.2 of this magazine. Its received end uses the electronic relay which is introduced here. The features of this electronic relay are: very high the release factor, most sensitive, low power consumed, worked stably and reliably. The circuit is simple, produced and regulated easily etc. It consists of six parts: the track transformer, 25Hz band pass filter, potential gate flip-flop, frequency selective amplifier, executing circuit and the rectified power source. This paper recommands briefly the working principles and the specifications of these six parts.
