Our guts are home to trillions of bacteria, and research over the last few decades has established how essential they are to ...

Researchers had also described the bacteria quickly spreading among neighboring cells. But Portnoy, who joined UPenn’s medical school in 1988, had found he could block this cell-to-cell spread by ...

These include some obvious mechanical activities such as endocytosis, cell motility and membrane resealing, but also others, such as replication and transcription. Taking the motor proteins as an ...

By observing that, in the presence of the protein, DNA moved much slower through pores in a gel, they confirmed that Bd0055 binds DNA. Deleting the gene turned out to be lethal in B. bacteriovorus ...

Oriented cell movements during convergent extension ultimately derive from the polarized localization of proteins that influence cell motility. A molecular description of this polarity is just ...

Due to its rigid structure, proline frequently causes stalls at ribosomes—the "protein factories" of the cell. All organisms use a specific factor to overcome these stalls. In bacteria ...

A) Time-lapse series of two cells making contact by gliding motility followed by TraA-TraA ... MYXO-CTERM sorting tag directs proteins to the cell surface via the type II secretion system. Molecular ...
