Researchers developed a new method to identify the sugar structures attached to proteins in various foods and organisms. They discovered that many of these sugar structures are different from what scientists previously thought based on standard biological pathways. Using advanced mass spectrometry technology, they created a database to quickly identify these novel sugar structures, which could help better understand how organisms modify their proteins.

PRMT5 promotes cellulase production by regulating the expression of cellulase gene eg2 through histone methylation in Ganoderma lucidum

Scientists discovered that a protein called PRMT5 controls how much cellulase enzyme the medicinal mushroom Ganoderma lucidum produces. When PRMT5 activates a specific gene called eg2 through a molecular modification of histone proteins, the mushroom produces more cellulase. This enzyme is valuable for breaking down plant waste into useful sugars for industrial and bioenergy applications. This research could help develop better enzyme-producing strains for industries that need cellulase.
