The digestive system breaks all proteins down into their amino acids so that they can enter thebloodstream. Cells then use the amino acids as building blocks to build enzymes and structural proteins. SeeHow Food Worksfor additional information....
Since proteins are the main constituents of cells, the decoding of the genome determines not only the size, shape, biochemical properties, and behavior of cells, but also the distinctive features of each species on Earth. One might have predicted that the information present in genomes would be...
Putting Proteolysis to Work How do cells use proteolysis to control their growth? One answer to this question has already been provided: by regulating the proteins that control cell cycle progression. But a more funda- mental answer to this question needs to address exactly how the regulation of...

Scientists at the EMBL in Grenoble, France, were the first to determine the structure of a ribosome-protein complex involved in carrying nascent proteins out of the cell. Their work, published today in Nature Structural and Molecular Biology, could increase understanding of illnesses such as cystic...
A happy cell is a balanced cell, but for every stupendously twisted protein it creates, it must tear the old ones asunder. That means untangling a convoluted pretzel-like mass for recycling. Cdc48 plays a critical role in unraveling the spent proteins.
Cells need to keep their genomic DNA unharmed to stay healthy and the scientists were able to visualize the process of DNA replication and damage directly in cells with an unprecedented detail. They discovered a fundamental mechanism of how proteins protect chromosomes while DNA is being copied (a...
Vesicles carry important things for a cell’s health – proteins, for example – into the cell. But they can also be hijacked by pathogens that can infect cells. But the question of how those pockets formed from membranes that were previously believed to be flat had stymied researchers...
How doimmune cellsmake daughter cells that are different form one another, rather than splitting into identical daughter cells? The team's paper, published this week online inScience, shows how one cell type can reliably produce cell diversity. Motile B cells that don't have life-long attachmen...
