Biomolecular Machines: Computers Making Computers?
http://biomolecularmachines.blogspot.com/2009/01/computer-making-computers.html
Thursday, January 1, 2009. An interesting article authored by Antoine Danchin from the Pasteur Institut was recently published and is sure to bring forth much discussion. Bacteria as computers making computers. The quantum teleportation experiments. Have demonstrated that information can be viewed as a fundamental irreducible property of physics ( informationalism. There are many interesting passages in this article. A few of these are going to be highlighted for discussion. Cellular processes are exquis...

Biomolecular Machines: January 2009
http://biomolecularmachines.blogspot.com/2009_01_01_archive.html
Monday, January 19, 2009. In order to demonstrate the validity of viewing cells as computers that are able to manipulate information, consider the following finding. The Ribosome: Perfectionist Protein-maker Trashes Errors. ScienceDaily (Jan. 9, 2009) — The enzyme machine that translates a cell's DNA code into the proteins of life is nothing if not an editorial perfectionist. We thought that once the mistake was made, it would have just gone on to make the next bond and the next,. Information. Materi...

Biomolecular Machines: Protein folding, Nanotubes and Engineering
http://biomolecularmachines.blogspot.com/2008/11/protein-folding-and-engineering.html
Tuesday, November 25, 2008. Protein folding, Nanotubes and Engineering. More on protein folding:. Many proteins have intricate folds and one of these fold types include the figure eight knot. Fold A team of researchers tried to figure out how these proteins are folded. At present, it is only known that the knot is formed quickly soon after polypeptide chain formation, with an unknown mechanism. The researchers tentatively propose:. Perhaps an an as of yet undiscovered knot-folding machine? I'll bet you t...

Friday, December 5, 2008. The Kinesin Motor Machine. How Tiny Cell Proteins Generate Force To 'Walk'. ScienceDaily (Dec. 4, 2008) — MIT researchers have shown how a cell motor protein exerts the force to move, enabling functions such as cell division. Kinesin, a motor protein that also carries neurotransmitters,. Along cellular beams known as microtubules. For the first time, the MIT team has shown at a molecular level how kinesin generates the force needed to step along the microtubules. Next, Lang's te...

Tuesday, November 25, 2008. Replication Machinery and Transcription Factories. How DNA Is Unwound So That Its Code Can Be Read. ScienceDaily (Nov. 24, 2008) — Researchers at The Scripps Research Institute have figured out how a macromolecular machine is able to unwind the long and twisted tangles of DNA within a cell's nucleus so that genetic information can be "read" and used to direct the synthesis of proteins, which have many specific functions in the body. Remarkable Unpacking and Repacking". What th...

Biomolecular Machines: Idle Control Units and Metabolomics
http://biomolecularmachines.blogspot.com/2008/12/idle-control-units-and-metabolomics.html
Friday, December 5, 2008. Idle Control Units and Metabolomics. Well designed cars have well designed idle control units. That spontaneously kick in to maintain the speed of the crankshaft within a pre-set range (usually 200rpm). An interesting study has demonstrated that 4 single celled organisms in two domains of life (bacteria and eukaryotes) uses the same number of biochemical reactions when optimizing growth. Spontaneous Reaction Silencing in Metabolic Optimization. Glucose metabolic network can be r...
