"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 ...

between its amino acid side chains. Proteins are the workhorses of cells. Learn how their functions are based on their three-dimensional structures, which emerge from a complex folding process.

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.
