Scientists have discovered that tRNAs can determine how long mRNAs exist in a cell, causing some messages to be stabilized and translated into more protein, while directing others to be degraded and ...

The tRNA has a four-base anticodon loop, and when a ribosome reading an mRNA within the E. coli cells encounter AGGA, it inserts the unnatural amino acid L-homoglutamine at that site.

This involves the formation of peptide bonds between amino acids bound to transfer RNA (tRNA) molecules that glide over the ribosome in very close proximity to each other, and elongate the peptide ...

This makes amino acids optically active chiral molecules with structures that are mirror images of each other and are not superimposable, just like our left and right hands (Fig. 1).

This region contains an amino acid that is often mutated in those with pontocerebellar hypoplasia. Samoil Sekulovski, the first author of the study, commented, “for us, this is an important indication ...

Proteins are life's molecular workhorses, doing everything from turning sunlight into food to fighting viruses. They are ...

All 20 amino acids were found to differently affect TORC1 using two 'pathways': Pib2 and Gtr. A pathway can be thought of as a specific chain reaction that leads to certain outcomes in a cell.
