Researcher offers clues on the origins of life
Date:4/5/2013

s a by-product of green plant life and bacteria that emerged.

Using a technique called top-down symmetric deconstruction, Blaber's lab has been able to identify small peptide building blocks capable of spontaneous assembly into specific and complex protein architectures. His recent work explored whether such building blocks can be comprised of only the 10 prebiotic amino acids and still fold.

His team has achieved foldability in proteins down to 12 amino acids about 80 percent of the way to proving his hypothesis.

If Blaber's theory holds, scientists may refocus where they look for evidence in the quest to understand where, and how, life began.

"Rather than a curious niche that life evolved into, the halophile environment now may take center stage as the likely location for key aspects of abiogenesis," he said. "Likewise, the role of the formation of proteins takes on additional importance in the earliest steps in the beginnings of life on Earth."
