WebOct 27, 2014 · Accordingly, a yeast cell is estimated to have ∼3,000 free 60S particles and a comparable number of free 40S particles, ∼8,000 Tae2 molecules , and only ∼200 Ltn1 molecules . In recognizing the stalled tRNA, Tae2 would additionally prevent the reassociation of free 40S subunits to the stalled 60S-peptidyl-tRNA complex due to … WebThe Stm1p was bound to the head of the 40S subunit and then snaked through the mRNA entry tunnel of the ribosome ( Ben-Shem et al. 2011 ). Interestingly, Stm1p appears to inhibit the function of 80S ribosomes ( Balagopal and Parker 2011) and to oppose eEF3 function ( Van Dyke et al. 2009 ).
