- n. A bacterial organelle that contains enzymes involved in carbon fixation.

The research team, led by co-first authors, research fellows David Savage and Bruno Afonso, attached a fluorescent tag to proteins involved in building the carboxysome, then grew the tagged bacteria under a microscope.
Silver's lab is looking into whether the carboxysome might be useful for optimizing the production of hydrogen by engineered bacteria.
Fluorescent labeling of proteins inside the carboxysome show that cyanobacteria create carboxysomes in numbers proportional to length and space them evenly along their longest axis.
"Knowledge about how cells create and deploy specialized factories like the carboxysome opens the way to creating other kinds of mini factories that could perform useful functions," said Richard Losick, Harvard University professor of molecular and cellular biology, who was not involved in the study.
The carboxysome may help solve this problem because its outer shell blocks out oxygen, protecting the enzymes inside from its toxic effects.
