Leveraging a genetically tractable alphaproteobacterium reveals molecular determinants of bacterial growth in fungal-decayed wood

Nathan M. Lewis, Irshad Ul Haq, Jonathan S. Schilling, Kathryn R. Fixen

This study investigates how a model brown rot fungus and a model Alphaproteobacterium interact with decayed wood, revealing bacterial preference for non-aromatic compounds and metal-induced stress responses.

Predicting compatibility between ferredoxins and the Fe protein of nitrogenase using in silico protein modeling

Adity Biswas, Katerina Trachtova, Kathryn R. Fixen

This study predicts ferredoxin compatibility with nitrogenase Fe protein using in silico docking, finding that shorter cofactor distances enhance electron tunneling and compatibility.
