Natural nanomachine in action
ID Number
2336
Description
Using a supercomputer to simulate the movement of atoms in a ribosome, researchers looked into the core of this protein-making nanomachine and took snapshots. The picture shows an amino acid (green) being delivered by transfer RNA (yellow) into a corridor (purple) in the ribosome. In the corridor, a series of chemical reactions will string together amino acids to make a protein. The research project, which tracked the movement of more than 2.6 million atoms, was the largest computer simulation of a biological structure to date. The results shed light on the manufacturing of proteins and could aid the search for new antibiotics, which typically work by disabling the ribosomes of bacteria.
