The Function of Two Radical-SAM Enzymes, HcgA and HcgG, in the Biosynthesis of the [Fe]-Hydrogenase Cofactor

In the biosynthesis of the iron-guanylylpyridinol (FeGP) cofactor, 6-carboxymethyl-5-methyl-4-hydroxy-2-pyridinol (1) is 3-methylated to form 2, then 4-guanylylated to form 3, and converted into the full cofactor. HcgA-G proteins catalyze the biosynthetic ...

Multimodal Response to Copper Binding in Superoxide Dismutase Dynamics

David Lyndon Emsley

Copper/zinc superoxide dismutase (SOD) is a homodimeric metalloenzyme that has been extensively studied as a benchmark for structure-function relationships in proteins, in particular because of its implication in the familial form of the neurodegenerative ...

The atomic-resolution crystal structure of activated [Fe]-hydrogenase

Xile Hu, Matthew Wodrich

Hydrogenases are promising templates for constructing new H-2-based catalysts. [Fe]-hydrogenase, which features an ironguanylylpyridinol (FeGP) cofactor, catalyses a reversible hydride transfer from H-2 to methenyl-tetrahydromethanopterin (methenyl-H4MPT+, ...

Towards artificial methanogenesis: biosynthesis of the [Fe]-hydrogenase cofactor and characterization of the semisynthetic hydrogenase

Xile Hu, Lichen Bai, Tao Xu

The greenhouse gas and energy carrier methane is produced on Earth mainly by methanogenic archaea. In the hydrogenotrophic methanogenic pathway the reduction of one CO2 to one methane molecule requires four molecules of H-2 containing eight electrons. Four ...
