Danish researches solve virus puzzle
...some encounters a pseudoknot it has to unravel the knot
before the reading can proceed. During this process the ribosome sometimes slips backwards and, like the letters making up a word, it now reads a new RNA sequence and hence uses another recipe to construct the protein. The researchers have found that...
MIT finds most complex protein knot ever seen
An MIT team has discovered the most complicated knot
ever seen in a protein, and they believe it may be... one protein - ubiquitin hydrolase. That complex knot
may hold some protective value for ubiquitin hydrolase, whose function is to rescue other proteins f...

Scientists map one of biology's critical light-sensing structures
...ose structures are known. The group speculates the knot
may help stabilize the protein so it can do its job of capturing light and triggering the cascade of downstream events under its control. "We think that without the knot, the protein conformational changes (prompted by light) would be too floppy to ...
