"The evidence for tryptophan in the Perseus molecular complex should encourage additional efforts to identify other amino acids in this region and in other star-forming regions," the scientists ...

Previously, we showed that pathogenic tuberin amino-acid substitutions disrupt the tuberin–hamartin complex. Here, we investigate how these mutations affect the role of tuberin in the control of ...

Amino acids act as nutrient signals to induce cell growth in addition to their role as protein building blocks. Cells can sense the availability of extracellular and intracellular amino acids and ...

For this purpose, it avails itself of complex machinery, with specific enzymes and RNA; this process can prove to be very costly for the cell. But why? What function does this amino acid have in ...

The branched structure is important as it shows that interstellar space could be the origin of more complex branched molecules, such as amino acids, that are necessary for life on Earth.
