Special Seminar - Professor Anders Liljas

Lund University

Evolution of protein synthesis

Biochemistry Seminar Room 231
Mar. 16, 2017
  • 12:00

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, there is no structural match between the code words and the corresponding amino acids. The tRNAs, ribosome, composed of a few RNA molecules and numerous proteins, display features that suggest how a simpler system may have been arranged. The tRNA synthetases and the elongation factors also have elements suggesting how a more primitive system could have been constructed.
