Asp218 participates with Asp213 to bind a Ca2+ atom into the S1 subsite of aminopeptidase A: a key element for substrate specificity.

13 Nov 2008 APA (aminopeptidase A; EC 3.4.11.7) is a membrane-bound zinc metallopeptidase, also activated by Ca(2+), involved in the formation of brain angiotensin III, which exerts a tonic stimulatory action on the central control of blood pressure in ... Read more...

The Miller volcanic spark discharge experiment.

15 Oct 2008 Miller's 1950s experiments used, besides the apparatus known in textbooks, one that generated a hot water mist in the spark flask, simulating a water vapor-rich volcanic eruption. We found the original extracts of this experiment in Miller's ... Read more...

An amino acid polymorphism in the couch potato gene forms the basis for climatic adaptation in Drosophila melanogaster.

11 Oct 2008 Diapause is the classic adaptation to seasonality in arthropods, and its expression can result in extreme lifespan extension as well as enhanced resistance to environmental challenges. Little is known about the underlying evolutionary genetic ... Read more...
