The Aspergillus nidulans cnxF gene and its involvement in molybdopterin biosynthesis. Molecular characterisation and analysis of in vivo generated mutants

, 1998
The product of the Aspergillus nidulans cnxF gene was found by biochemical analysis of cnxF mutants to be involved in the conversion of precursor Z to molybdopterin, Mutants cnxF1242 and cnxF8 accumulate precursor Z, while the level of molybdopterin is ...

Room‐temperature crystal structure of a metal‐dependent W‐formate dehydrogenase by serial synchrotron crystallography

Acta Crystallographica Section D, Volume 82, Issue 9, Page 1072-1081, September 2026.
We report a room‐temperature serial synchrotron X‐ray crystallographic structural analysis of Nitratidesulfovibrio vulgaris formate dehydrogenase AB, an enzyme that reduces CO2 to formate.Metal‐dependent formate dehydrogenases (Fdhs) are a promising research target in efforts to mitigate climate change by developing active, efficient, selective and ...

Genomic Insights Into the Multimetal Resilience and Biofilm‐Templated Nanorod Biosynthesis of Stenotrophomonas bentonitica BII‐R7: Bioremediation and Green Nanotechnology Implications

Microbial Biotechnology, Volume 19, Issue 9, September 2026.
Biofilm extracellular polymeric substances (EPS) in Stenotrophomonas bentonitica BII‐R7 direct the formation of crystalline trigonal selenium nanorods. Comparative genomics identifies a unique genetic toolkit underpinning EPS composition and metal resilience, positioning this strain as a platform for bioremediation and green nanomaterial synthesis ...

Cleavage of the moaX-encoded fused molybdopterin synthase from Mycobacterium tuberculosis is necessary for activity [PDF]

, 2015
Background: Molybdopterin cofactor (MoCo) biosynthesis in Mycobacterium tuberculosis is associated with a multiplicity of genes encoding several enzymes in the pathway, including the molybdopterin (MPT) synthase, a hetero tetramer comprising two MoaD and

Rearrangement reactions in the biosynthesis of molybdopterin [PDF]

European Journal of Biochemistry, 1998
The genes moaABC of Escherichia coli were ligated into the expression vector pNCO113. The resulting plasmid was transformed into a moeA mutant of E. coli. From cultures of the recombinant strain, a pteridine designated compound Z could be isolated at 5 mg/liter. Compound Z is a product of precursor Z, a biosynthetic precursor of molybdopterin. Cultures

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, Volume 600, Issue 15, Page 2094-2107, August 2026.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Understanding the Catalytic Determinant role of Diaphorase‐Like Subunit in Formate Dehydrogenases via Redox Couples

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A unique mechanism of catalytic bias regulated by diaphorase‐like subunit in formate dehydrogenase from Rhodobacter aestuarii is revealed. The diaphorase‐like subunit functions act as a biological “voltage rheostat” that controls the slow release of NADH to regulate redox balance, biasing the enzyme's catalytic preference toward CO2 reduction over ...
