The elongation cycle of protein synthesis consists of three major steps. It begins with a ribosome that contains peptidyl-tRNA (or initiator tRNA) in the P site and a free codon in the A site. During ...

mRNAs program the synthesis of proteins in cells, and their functional lifetimes are dynamically regulated. LMU researchers have now shown why blueprints that are more difficult to decipher have ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 108, No. 24 (June 14, 2011), pp. 9827-9832 (6 pages) The crucial process of aminoacyl-tRNA delivery to the ...

(Philadelphia, PA) – The fact that ribosome recycling factor (RRF) looks a lot like transfer RNA (tRNA) has not been lost on scientists. After all, both molecules are an important part of a bacteria's ...

The process of 'translation' in protein synthesis involves formation of a peptide bond between two amino acids that are attached to two distinct transfer RNAs (tRNAs). For long, scientists have been ...

"Obtaining tRNA molecules linked to peptides, similar to those inside the ribosome during protein synthesis, has remained a dream of many researchers in the field for almost two decades," Polikanov ...

A new technique reveals ribosome cooperativity, providing new insights into protein production. Researchers from Marvin Tanenbaum’s group at the Hubrecht Institute (Utrecht, Netherlands) have ...

CHAMPAIGN, Ill. — Two new studies reveal in unprecedented detail how the ribosome interacts with other molecules to assemble new proteins and guide them toward their destination in biological cells.

The molecular machines that cells use to build proteins are backed by a billion years of evolution. In that time, these machines—ribosomes—have become exceptionally good at forging amide bonds between ...

Scientists at St. Jude Children’s Research Hospital report that human ribosomes decode messenger RNA (mRNA) 10 times slower than bacterial ribosomes, but do so more accurately. The study “mRNA ...
