Webbanswered at this time: Does all protein synthesis occurby a single additionofanaminoacyl unit to a growing chainonthe ribosome, or do separate, small, peptide intermediates form and then link together? Loftfield and colleagues (71, 72) showedthat there are no small peptide intermediates. Butin whichdirection did the nascent peptide chaingrow ...
Webb3 mars 2024 · Synthesis proceeds from the N-terminus to the C-terminus of the protein. The ribosomes “read” the mRNA in the 5′ to 3′ direction. Active translation occurs on polyribosomes (also termed polysomes). This means that more than one ribosome can be bound to and translate a given mRNA at any one time.
