Chance Discovery Finds Protein Derived from E.Coli that Kills the Bacteria Itself

Chance Discovery Finds Protein Derived from E.Coli that Kills the Bacteria ItselfPublished in the journal Molecular Microbiology, a recent chance discovery has found something amazing.  While doing a research, Professor Jeremy Lakey found that a protein derived from E.  Coli killed the bacteria itself.

The discovery happened while the research team from the Newcastle University was studying a protein derived from E. coli bacteria. Dubbed Colicin N, this protein was able to kill the whole bacteria in very efficient way.

Professor Lakey said that he was unable to believe what they just found.  Just one molecule of this protein was enough to kill the whole cell.

The team divided the protein in to three parts namely a receptor, a toxic part and a `tail-like' part.  They tried to find out the effect of each part on the bacteria.  They found that tail of the protein when introduced to environment of the bacteria, it killed them.

From this the researchers concluded that new antibiotics could be developed from this part of protein fight E.  Coli.  The experiment was repeated a number of times to find similar results.

"This was a result that we weren't expecting.  We don't know how this is all working so we will be looking at this in much more detail but it looks promising", said Dr.  Chris Johnson, the Researcher who made the key discovery.
