Researchers implanted laboratory-made synthetic protein (DX)into E. coli cells , finding that DX protein combined with molecular ATP in cells , stopping cells division ,while these cells are still grow . This research provides a new method to understand the behavior of pathogens which can evade antibiotics , and related research performance published in “science “.
"If you implanted a protein created in a test tube into cells, the protein will function in cells ," Charles Putnam said, "Do you think cell know it yet? Cells are chewing it, or spiting it ? This discovery will make progress in the development of new drugs. "ATP is the energy currency of life," Putnam said , in biological systems reactions , a certain energy are essential to the drive the combination of ATP phosphodiester bond . DX protein binding consume the energy of ATP in cells , destroying the cells normal metabolic activities , preventing cells division , but the cells are still growing .
After the exposing of E. coli , it will become elongate element from generally spherical filaments. In filamentous bacteria, dense intracellular lipid structure is divided , forming a cell with same length , the researchers calls this unusual structure as internal liposomes."These dense lipid structures are forming very regular area, they gradually formed along filamentous cells, they look like a defense mechanism that allows cells to self-division." Charles Putnam said. This unique process of adaptation, never observed in bacterial cells, but it is the only single cell organisms .
