Bacteria eats greenhouse gas with a side of protein

Read the full story from Northwestern University.

With the ability to leach heavy metals from the environment and digest a potent greenhouse gas, methanotrophic bacteria pull double duty when it comes to cleaning up the environment.

But before researchers can explore potential conservation applications, they first must better understand the bacteria’s basic physiological processes. Northwestern University’s Amy C. Rosenzweig recently has constructed another section of the puzzle. Her laboratory has identified two never-before-studied proteins, called MbnB and MbnC, as partially responsible for the bacteria’s inner workings.

“Our findings extend far beyond methanotrophic bacteria,” said Rosenzweig, the Weinberg Family Distinguished Professor of Life Sciences and professor of molecular biosciences and chemistry in Northwestern’s Weinberg College of Arts and Sciences. “These two proteins are found in a range of other bacteria, including human pathogens.”

The paper publishes tomorrow, March 23, in the journal Science.
