Bacteria stockpile protein like I stockpile coffee before finals.

In a groundbreaking exploration of cellular behavior, scientists at the University of Washington have shed light on the intriguing phenomenon of protein stockpiling in bacteria.

Bacteria stockpile protein like I stockpile coffee before finals.
In a new study, UW researchers explored why cells “stockpile” some proteins that are required for growth. Shown here is a series of “heat map” images that detail the abundance of a required protein over five bacterial generations — red represents more protein within the cell, while dark blue represents less. When the researchers disabled the gene necessary to make the protein, the abundance of that protein diminished in each generation (top row). The cells in the bottom row had a functioning gene, so the protein remained abundant. Photo: H. James Cho et. al/Science Advances

As far as research subjects go, it’s not always easy to find common ground with a single-celled bacterium. Yet the more Paul Wiggins studies his model bacteria, Acinetobacter baylyi, the more he sees surprising commonalities between their behavior and our own as humans.

“It was mortifying to be stumped for so long by what appeared to be completely counterintuitive behavior only to realize that I engage in exactly the same behavior everyday,” said Wiggins, an associate professor of both physics and bioengineering at the University of Washington.
