  Mode of inhibition of globin synthesis by m7G5'p and m7G5'ppp.

  Suzuki H.

  J Biochem. 1978 Nov;84(5):1125-32.

  The mode of inhibition of rabbit globin synthesis by m7G5'p and m7G5'ppp ("cap analogs") was studied using the rabbit reticulocyte lysate system. The rate of globin synthesis was measured at various concentrations of both f[35S]Met-tRNAf and the cap analogs. The cap analogs were found to inhibit competitively the incorporation of f[35S]Met into hot trichloroacetic acid-insoluble material. Nascent chains prelabelled with f[35S]Met were released at various concentrations of m7G5'ppp. The release of nascent chains was not inhibited by m7G5'p (Suzuki, H. (1976) FEBS Lett. 72, 309) and m7G5'ppp, and it is therefore concluded that the cap analogs inhibit a step of initiation of globin synthesis. Under conditions such that the elongation of nascent chains was inhibited by sparsomycin, the formation of an 80S/fMet-tRNAf was inhibited by the cap analogs, but not that of a 40S/fMet-tRNAf complex. These data suggest that a factor which is required for the binding of globin mRNA with 40S/fMet-tRNAf complex forms an inactive complex with the cap analogs, so that the cap analogs inhibit globin synthesis.
