Ribosome transit time

In poliovims infected cells and presumably in cells infected by other picomaviruses, the polysome complex formed with viral mRNA is large. The average number of ribosomes in the largest polysomes (jSOS) is about 35 per viral mRNA (5)> due at least partially to the large size of the viral mRNA (2.5 x 10 daltons (6) ). The transit time for a ribosome to traverse a molecule of picomavirus mRNA is approximately 10 min (7, 8) early in infection. The rate of chain elongation is about 205 to 225 amino acids per min. This rate is considerably slower than the rate of synthesis of the a and B chains of hemoglobin, namely 600 and 400 amino acids per min 9) respectively. [Pg.127]
