Study finds plant enzyme function changes with location in cell
...st than it did in the plants: It inserted a double bond in a different place along the fatty acid carbon chain. The scientists knew that, in the plant cells, the enzyme is tagged with an "address signal" that directs it to the plant cells' chloroplasts, the green organelles within plant cells where photo...Rutgers chemist uses NMR to elucidate protein-DNA interaction

...lter someone's social conditions, to get people to bond with others," she continued. "If we could identify a mechanism by which social interaction helps wounds heal, then we might be able to provide a pharmacological aid to facilitate healing in socially isolated people and other individuals at risk." ...Sweet success in targeting sugar molecules to cells in living animals
...cell's biology; and the components form a covalent bond with one another in a highly selective manner. In the research reported in Nature, Bertozzi and her colleagues describe the first use of their cell-surface engineering technique in living animals. Previously, they had only applied it to cultured cell...Scientists reinvent DNA as template to produce organic molecules
...sequences (A matches T, G matches C) spontaneously bond together, their associated organic molecules undergo a chemical reaction to generate a product. As a result, the DNA strands essentially serve as a miniature, sequence-programmable assembly line for products of chemical synthesis. Because the resulti...Synthesized molecules studied as weapon to stop cell division in cancer cells
...logical function. Pin1 works by changing a peptide bond within Cdc25 from the trans shape (a flattened-Z shape) to the cis U-shape and back. This a simple change -- the swing of an arm one way or another to open or close the U results in a large conformation change in a protein. The researchers synthesi...Images of 'tail' of protein needed for cell multiplication suggest anticancer drug targets
...iately after activating NEDD8, E1 forms a chemical bond with this protein. E1 then transfers NEDD8 to E2. Finally, E2 transfers NEDD8 to the E3 enzyme, which completes the workshop's job by binding NEDD8 to Cul1.
