Researchers at Münster University are studying key mechanisms in the regulation of energy metabolism in plants and, using a new method of in vivo biosensor technology, they have opened the door to monitoring, in real time, what effects environmental changes have on the central redox metabolism. The study has appeared as an advance publication in the journal "The Plant Cell".
Proteins take on an important function in photosynthesis. In order to be able to work purposefully, they change their chemical form after they have been produced in a cell. The role of the “driver” is played by enzymes. Researchers have now identified enzymes, which facilitate reactions in a twofold way. The study has been published in “Molecular Systems Biology”.
A metabolic pathway that has occupied plant scientists for decades is the oxidative pentose-phosphate pathway, which leads to the conversion of carbohydrates into energy equivalents. Researchers at Münster Universityfound that an important membrane protein is distributed to two cell organelles simultaneously, to provide reduction power at both locations.
The human immune system can easily recognize fungi because their cells are surrounded by a solid cell wall of chitin and other complex sugars. Researchers at Münster University found that a fungal pathogen, Cryptococcus neoformans, uses an enzyme to hide from the human immune system. The study was published in the journal "PNAS".
Not only DNA and proteins, complex sugars also speak their own language/study in JACS
Chitosans are probably the most versatile and promising functional biopolymers. Chitosans can make plants resistant to diseases, promote their growth, and protect them from heat or drought stress. Under chitosan dressings, even large wounds can heal without scars, chitosan nanoparticles can transport drugs across the blood/brain barrier, and chitosans can replace antibiotics in animal fattening as antimicrobial and immunostimulating feed additives. But of course, chitosans are not miracle cures either: there are many different chitosans, and for each application you have to find exactly the right one if it is to work. Unfortunately, we still understand far too little which chitosan has which effect and how the different chitosans unfold their effects. Only when we understand this, when we understand the "language" of chitosan, we can use it in a targeted way. Researchers from Münster have
now come a long way towards achieving this goal...
