Evolution of protein synthesis

Professor Emeritus Anders Liljas, Department of Biochemistry and Structural Biology, Lund University, Sweden

The genetic code is universal, and so is the complex machinery used for translation or protein synthesis. Is there any way to get an insight into the evolution of the system?

The genetic code is distinctly non-random, but there is no structural match between the code words and the translation to amino acids. The ribosome, composed of a few RNA molecules and numerous proteins, displays features that suggest how a simpler system may have been arranged. The tRNA synthetases and the elongation factors also have elements that suggest how a more primitive system could have been constructed.
