This story in ScienceDaily shows how finely tuned biological logic is. This split-second timing of a vital process in cellular life could never be achieved by hit-and-miss means, only by very precise logic.
Researchers from the RUB-Department of Biophysics of Prof. Dr. Klaus Gerwert have succeeded in providing evidence that a protein is capable of creating a water molecule chain for a few milliseconds for the directed proton transfer. The combination of vibrational spectroscopy and biomolecular simulations showed the proton-pump mechanism of a cell-membrane protein in atomic detail. The researchers demonstrated that protein-bound water molecules play a decisive role in the function.
Protein-bound water is decisive: specific proteins can transport protons from one side (uptake side) of the cell membrane to the other side (release side)--a central process in biological energy conversion.

About Me
- Nobilangelo
- My Christian name is pronounced 'noble-arn-jillo' (i.e., both o's are long, so the first two syllables rhyme with 'noble' not 'hobble'--yes, I know that's obvious, because there's only one 'b' between the 'o' and the 'i', but some people seem to see two b's, hence the English lesson). My surname is pronounced kerra-marliss. I was born, bred and educated in New Zealand, except for an international systems-engineer's course in San Antonio, Texas. I am born-again Christian, a thinker with a very practical turn of mind, a scientist with a particular interest in planet-friendly energy and neuroscience, an engineer (mechanical, industrial and IT systems), an inventor, a Member of the American Association for the Advancement of Science, a writer and poet, a naturist, a designer in different fields, an arranger and composer of symphonic music, a multi-award-winning IT journalist, a photographer, and a practitioner at various times in other hands-on fields including building, metalwork, woodwork, stained-glass and landscaping.
