Lighting Conditions Influence the Dynamics of Protease Synthesis and Proteasomal Activity in the White Rot Fungus Cerrena unicolor.

摘要: Recent transcriptomic and biochemical studies have revealed that light influences the global gene expression profile metabolism of white-rot fungus Cerrena unicolor. Here, we aimed to reveal involvement proteases ubiquitin-mediated proteolysis by 26S proteasome in response this white, red, blue green lighting conditions darkness. The changes C. unicolor genes putatively engaged were found be unique specific applied wavelength light. It was also demonstrated activity culture fluid mycelium measured using natural synthetic substrates regulated substrate-dependent. A clear influence on protein turnover qualitative quantitative hydrolytic degradation proteins catalyzed various types shown. analysis associated with showed a key role ATP-dependent initial stages adaptation fungal cells stress factors. suggested light-sensing pathways are cross-linked signaling secretion presumably serving as regulatory molecules.
