New, automated tool successfully classifies and relates proteins in unprecedented way

...e too limited todescribe the many complex location patterns we found. Of course, theother drawback of term-based approaches is that they have to beassigned manually by database curators, and this is often notconsistent between different curators," said Murphy.Murphy and his colleagues are currently amassing m...

For example, Wolbachia can manufacture some essential metabolic coenzymes, which do not appear to be made by its host. Conversely, it cannot synthesize amino acids and a variety of othe...

Researchers trace evolution to relatively simple genetic changes

...Now, Kingsley said, "it turns out that armor plate patterns in the fish are controlled by the same gene that creates this clinical disease in humans. And this finding is related to the old argument whether Nature can use the same genes and create other traits in other animals." Ordinarily, "you wouldn't look...
