How bacteria form Z-rings at their center and split them into two parts.

Cell division is the most critical mechanism in the life process of the body.
25 years, we know that bacteria divide into two parts by forming a Z-ring in their center, which they use to cut themselves into two child cells.
team of international scientists from the United States, the United Kingdom and the Netherlands has successfully discovered how bacteria do this through advanced microscope technology.
study was published February 17 in The Science.
the formation of bacterial cell walls is similar to masonry, by building bricks on moving scaffolding.
molecules are bricklayers, proteins as scaffolding.
bacteria build a new cell wall from the outside by using multiple molecular "bricklayers", a process that takes about 15 minutes.
Surprisingly, molecular
bricklayers" move "step" along the inside of the cell wall being built;
researchers looked at individual bacteria using advanced microscopes to investigate the process.
this involves placing colored labels on cell wall materials.
each time they change color, they can see bacteria building cell walls from the outside.
by changing the color of the building material, there would be a break of only a few seconds in between, and the researchers saw that this was not a gradual process, but a process that occurred in different locations at a time.
drives all this is FtsZ, a protein that produces an arched polymer that moves through a "step-by-step" phenomenon.
Ces Dekker, co-author of the article using protein as a scaffolding, explains: "With a stepper, we can change the form of motion by adding something to the front, while also removing something from the back.
our study shows that cells also use this phenomenon to build cell walls.
" cell walls are built with the help of many collaborative proteins, and FtsZ is the most important part.
" New Discovery has solved the 25-year-old puzzle of how FtsZ coordinates cell division, and proteins are like scaffolding, building work on top of it, but it's not rolling scaffolding, it's fixed, which makes proteins need to constantly update themselves.
" cells continue to form new scaffolding to help build cell walls, for example, when the right-hand FtsZ scaffolding is generated, the left-hand FtsZ scaffolding breaks down and the FtsZ scaffolding moves along the cell wall.
allows cells to build a new cell wall in 10-15 minutes.
, other proteins ensure that DNA is properly separated between two child cells, or that membranes are properly closed, and so on.
nanoboxes The study is a collaborative project involving scientists from four scientific groups in the United States, the United Kingdom and the Netherlands.
study involved the production of nanostructures, where bacteria are precisely fixed.
by placing the nanobox upright on a microscope, we were able to see the cross-section of the cell very clearly, which gives us an excellent view of the dynamics of the FtsZ molecule.
Dekker explains.
the study is fundamental in nature, Dekker believes this type of study may have practical benefits in the future.
once we have a thorough understanding of how bacterial cells divide, it could pave the way for alternative antibiotics," he said.
's still a long way from that, but if we can target bacterial cell division, we may have new ways to fight disease-causing bacteria in the future.
