Abstract | Full text | PDF | PubMed | Cited on BioMed Central | F1000 Biology |  Editor’s summary

The relatively high zinc content of living cells and its role as cofactor in many key enzymes and RNA structures might reflect the origin of life in zinc-rich environments.

Hypothesis   Open Access Highly Accessed

On the origin of life in the Zinc world: 1. Photosynthesizing, porous edifices built of hydrothermally precipitated zinc sulfide as cradles of life on Earth

Armen Y Mulkidjanian Biology Direct 2009, 4:26 (24 August 2009)

Abstract | Full text | PDF | PubMed | Cited on BioMed Central |  Editor’s summary

Life may have emerged owing to the ability of porous, hydrothermal zinc sulfide precipitates to store solar energy and reduce atmospheric carbon dioxide, providing nourishment and shelter for the first organisms.
