The protein folding revolution What a fantastic video! Science Magazine uses great visuals to engage the question of the protein folding problem. This video illustrates some great advances to biochemistry in recent years concerning protein folding.
Balancing oxidative protein folding: The influences of reducing pathways on disulfide bond formation
According to the researchers’ models, one major aspect of the chromosome’s folding process is the formation of nested loops. First, a ring-shaped motor protein (red) lands on DNA and extrudes a loop. Later, a second protein (blue) extrudes loops on top of that one. When many such molecules across the entire length of the DNA do this, the chromosome compacts.
