Role of p-quinones in regulation of glucose-6-phosphate metabolism

Molecular mechanism of quinone signaling mediated through S-quinonization of a YodB family repressor QsrR

“…More recently, vitamin K 2 , a derivative of menadione, was discovered to function as an important electron carrier in Drosophila mitochondria to help maintain normal ATP production (8). A disordered quinone pool would severely affect the respiratory systems of Drosophila, leading to subsequent changes in cellular metabolism (9)(10)(11). Meanwhile, quinone molecules are also considered a source of exogenous stress: a variety of toxins and antimicrobial compounds contain quinone, such as cercosporin and anthracycline (12)(13)(14).…”
