summary:a man named Levinson and he belives that kidney cells transporting ions, and could be well suited to making a miniature battery.He suggests that such biobatteries might be ideal for powering devices inserted in the body, such as insulin pumps or pacemakers.and so he went for it
Questions: What reactions does this enzyme catalyze?it transports ions to the kidney
How is the cell affected if this enzyme is removed? i think it effects it in a bad way because the ions are needed for transporting information
List three things you learned from this article in your own words.ions are transported to the kidneys,the cell culture can draw oxygen, and producing biobatteries with the kind of voltages needed to run medical devices.
What impact would the absence of this molecule have on the cell? bad we need them to help transport

New Way To Identify, Evolve Novel Enzymes
The intricate interplay of proteins and other chemicals that underlies most biological activities requires the participation of enzymes, specialized molecules that accelerate chemical reactions between molecules. The creation of totally new enzymes can help improve the synthesis of chemicals and pharmaceuticals, devise new tools for molecular biology research, and develop new therapies. If a particular protein induced the RNA substrates to join, resulting in a significantly larger molecule, that signified the protein was an active enzyme.The investigators could select out the larger RNA strands, generate more of the enzymes, and repeat the experiment. The induction of random mutations to produce different forms of the enzymes and reducing the time allowed for the splicing reaction enabled the development of more efficient versions by means of guided evolution.

Summary:
There is a successful electrical connection between a carbon nanotube and hydrogenase. Hydrogenases show as a powerful catalysts. They can be used for hydrogen in fuel cells, which can produce electricity no pollution for motor vehicles, portable electronics, and other devices. Scientist have dound difficulty in putting these enzymes into electrical devices. They do not form good electrical connections. Metals such as platinum are needed to perform. They combined hydrogenase enzymes with carbon nanotubes, submicroscopic strands of pure carbon to make sure that they are good electrical conductors.

Summary: When using mice that had pre-existing cancers the McGill team disabled the function of the enzyme, FAK , in the mammory gland. When they isloated FAK they stopped the progression of the tumor. This showed that FAK is vital in the Progression of the tumor from premalignant to a malignant state in the mammarry tumor system . This discovery was also linked to an earlier discovery that the enzyme beta1-integrin was similary vital in the initiation of tumor growth and development of breast cancer in the mice.
