Cyanide compounds discovered in meteorites may hold clues to the origin of life

So this was a bit of a mixed bag for me. It’s really amazing how much we can learn from meteorites, and certainly if free cyanide is important for abiogenesis, finding extraterrestrial sources like this is interesting.

On, the other hand, I kind of expected more. The compounds they found are very simple (13 atom iron complexes), and it feels a little trivial to compare them to hydrogenase. Both have Fe, CN, and CO, but hydrogenase is a protein. Still, I guess if the simple iron cyanocarbonyl complexes can be shown to have some catalytic activity, that would be significant.
