New study reveals the protein that makes phosphate chains in yeast

... we speculate that it sends them straight to the vacuole for storage." Vtc4p is partly embedded in the ... probably transfers the polyphosphate chain to the vacuole as it produces it. The researchers determined ... Because the VTC can move from the membrane of the vacuole to that of the cell, it could assemble phosphate ...

Mouse can do without man's most treasured genes

... garbage dump. "The main function of the vacuole is to contain and degrade cellular wastes and toxins," Zhang said. "In humans, the absence of vacuole proteins causes those wastes and toxins to ... reproductive age. As a result, "many of these vacuole proteins are not so 'essential' to the mouse," ...

Cow stomach holds key to turning corn into biofuel

... part of the plant cell, called the vacuole. The vacuole is a safe place to store the enzyme until the plant is harvested. The enzyme will collect in the vacuole with other cellular waste products Because it is only in the vacuole of the green tissues of plant cells, the enzyme ...

Legionnaire's bacterial proteins work together to survive

... What makes this pathogen special is that it can control transport of the vacuole formed after macrophages ingest the bacterium, Roy said. It hijacks the vacuole and directs it to be transported to a nutrient-rich organelle called the ...

Comparative genomics reveals molecular evolution of Q fever pathogen

... cells in the body that usually provide protection against invading pathogens. The pathogen has the remarkable ability to replicate in a lysosome-like vacuole of macrophages, an extremely harsh intracellular environment that usually protects the body from infection by breaking down invading pathogens. The ...

Cornell researcher seeks clues to how tuberculosis infects cells

... health and their response to stress. The researchers have also created real-time readouts that measure conditions within the tuberculosis-containing vacuole at any time during the immune system's process. "Our goal is to develop these bacterial fitness readouts to screen small molecule libraries for ...

Breast tumors in mice eradicated using cancer vaccine

... cell, they are engulfed by a phagocytic vacuole where they get killed�whereupon their proteins ... But Listeria has evolved to escape from this vacuole and survive inside the cytosol of ... some of the bacteria are destroyed in the vacuole that feeds the MHC class II pathway of antigen ...

Plant studies reveal how, where seeds store iron

... soil can limit plant growth. Our study suggests that iron storage in the vacuole is a promising, and, before now, largely unexplored target for increasing ... how iron is stored by plants. The researchers say the stored iron in the vacuole is a key source of iron for developing seedlings. Seedlings that do not ...

Chlamydia parasite lives off our fat

... to synthesizing ATP, all while living inside a membrane-bounded vacuole that provides a protected, fertile environment for the bacteria to grow ... found that Chlamydia not only directs lipid droplets to its protective vacuole but also causes the proliferation of new lipid droplets on the host. The ...

Protein found to shield pancreatic cancer cells from self-destruction

... cell organ, or organelle. This autophagosome then merges with a digestive organelle called a lysosome and everything inside is consumed, leaving the vacuole and a residue of digested material. If enough of this happens, the cell dies. Gabriel Lopez-Berestein, M.D., professor of experimental ...
