Textbook images show peptidoglycan as straight and ordered. The biopolymer peptidoglycan that makes up bacterial cell walls was always assumed to be highly ordered. Textbook images like the one below ...

Planctomycetes are bacteria that lack peptidoglycan in their cell walls and possess membrane-bound intracellular compartments, some of which may be analogous to the nucleus and the mitochondria of ...

Prokaryotes are unicellular organisms that lack membrane-bound structures. This article details the structure of prokaryotic cells and provides examples of prokaryotic organisms.

A Cornell-led collaboration has devised a potentially low-cost method for producing antibodies for therapeutic treatments.

Using mutant bacteria to study how changes in membrane proteins affect cell functions Fluctuations in phospholipid composition can cause changes in membrane protein function, providing a ...

Bacteria are traditionally imagined as single-cell organisms, spread out sparsely over surfaces or suspended in liquids, but in many environments the true bacterial mode of growth is in sticky ...

More important, these strings were found to be continuous along the bacterial cells passing through the cell–cell junctions. This indicates that the strings serve an important function in maintaining ...

MIT chemists have discovered the structure of a protein that can pump toxic molecules out of bacterial cells. Proteins similar to this one, which is found in E. coli, are believed to help bacteria ...

Clusters of a toxic bacterial protein have a surprising structure, differing from similar clumps associated with Alzheimer’s and Parkinson’s in humans, scientists report in the Feb. 24 Science ...
