But with our planet as their guide, astrobiologists are forced to acknowledge that oxygen may be the least likely thing they will ever see — genetic evidence suggests the complex oxygen - producing photosynthetic pathway pioneered by cyanobacteria is an extraordinary evolutionary innovation that only appeared once throughout the entire multi-billion-year history of Earth's biosphere.

The pioneering research was performed on a photosynthetic LH1 - RC complex from the bacterium Blastochloris viridis, which can harvest and use light at wavelengths over 1,000 nm.

The methodology is demonstrated on two model systems: the time - dependent spontaneous dissociation of photosynthetic light - harvesting antenna complexes and direct observation of DNA strands binding and unbinding in solution.

As proposed by Andrew Goldsworthy in 1987, cyanobacteria and later chloroplast - related protists and plants developed after microbes that used a purple pigment bacteriorhodopsin that absorbs green light dominated the oceans, and so the new photosynthetic cyanobacteria were forced to use the left - over light with chlorophyll that reflects green light, which was too complex to change even after purple - reflecting photosynthetic lifeforms were no longer dominant (Debora MacKenzie, New Scientist, September 10, 2010 — more on the evolution of photosynthetic life and plants on Earth).

Historically, photosynthetic bacteria pumped oxygen into the oceans for billions of years, setting the stage for complex multicellular life.

Eros is an ortholog of the plant protein Ycf4, which is necessary for expression of proteins of the photosynthetic photosystem 1 complex, itself also an NADPH oxio - reductase.

The program focuses on development of transition - metal complexes that are inspired by the natural photosynthetic enzymes such as nitrogenases, hydrogenases, and the oxygen - evolving complex of photosystem II with the goal of designing catalysts that are chemically stable, active, and highly selective for specific chemical targets.
