The bacteria altered to lack SRP components were able to adapt and survive gradual increases in acid resulting from their own metabolism, suggesting a backup pathway was in place.

Bacterial secretion is the process by which bacteria release substances to their surroundings, including other cells. Bacteria achieve this using dedicated secretion systems that transport ...

The SRP/SR system is present in all three kingdoms of life, from humans and other animals, to plants and fungi, to bacteria and primitive archaean organisms.

Every secretion system in Y. entomophaga was knocked out until no more were left, yet the bacteria were still able to secrete YenTc. The researchers then used fluorescence microscopy to observe ...

Most of the genetic material of bacteria is packed into a long, circular DNA molecule. However, type IV secretion systems and ...
