Metalloenzymes and iron-sulfur proteins

Proton-coupled electron transfer in IscR, the Escherichia coli iron-sulfur cluster regulator

This paper identifies proton-coupled electron transfer (PCET) in IscR, an Escherichia coli iron-sulfur cluster regulator, through spectroscopic analyses and defines its redox behavior and functional implications.

Redox Regulation in O2-Tolerant Hydrogenases: Insights from two homologues.

This study compares two [FeFe] hydrogenases, showing that TgHydA1 remains more stable under oxygen than CbHydA1 due to slower reactivation rates.

The -hydrogenase SoHydAB of Shewanella oneidensis - An Atypical M2(D)-type Enzyme that Drives Formate Oxidation

This paper characterizes SoHydAB, a [FeFe]-hydrogenase in Shewanella oneidensis, showing its unique electron acceptor and metabolic role in formate oxidation.

Predicting cyanobacterial oxic diazotrophy and prioritizing candidate protein families beyond known Nif proteins

The paper predicts cyanobacterial diazotrophy using protein-family content and prioritizes candidate protein families for experimental validation.
