E. coli Cell Envelope Protein Data Collection

  • Well thought out
  • Narrowly focused
Is it any surprise that E. coli, the most studied bacterial cell, also has the most specialized databases? The E. coli Cell Envelope Protein Data Collection provides researchers with access to yet another useful source of information. Membrane proteins are targeted for that portion of the cell by signal sequences in the polypeptide chain. The site provides visitors with a list of the 452 signal sequences in E. coli cell envelope proteins, as well as a listing of proteins sorted by location in the inner membrane, outer membrane, or periplasm. One can sort enzymes by size and also by functionality. The designers seem to have considered every possibility on this one. Though narrowly focused, it is a very useful site for E. coli researchers.

Scientifically Studying Ecstasy

MDMA (commonly known as the empathogen “ecstasy”) is classified as a Schedule 1 drug, which is reserved for compounds with no accepted medical use and a high abuse potential. Two researchers from Stanford, however, call for a rigorous scientific exploration of MDMA's effects to identify precisely how the drug works, the data from which could be used to develop therapeutic compounds.

Do you agree that ecstasy should be studied for its potential therapeutic benefits?
