Nanosecond photoreduction of inducible nitric oxide synthase by a Ru-diimine electron tunneling wire bound distant from the active site [PDF]

, 2009
A Ru-diimine wire, [(4,4′,5,5′-tetramethylbipyridine)_2Ru(F_9bp)]^(2+) (tmRu-F_9bp, where F_9bp is 4-methyl-4′-methylperfluorobiphenylbipyridine), binds tightly to the oxidase domain of inducible nitric oxide synthase (iNOSoxy). The binding of tmRu-F_9bp

In Vivo Biosynthesis and Direct Incorporation of Noncanonical Amino Acids into Proteins

ChemBioChem, Volume 26, Issue 22, November 17, 2025.
This review evaluates engineered (semi)autonomous cell systems for the biosynthesis and incorporation of noncanonical amino acids (ncAAs) into proteins. While semi‐autonomous cells convert supplied precursors into ncAAs autonomous cells integrate biosynthetic pathways that produce these building blocks intracellularly.

The pterin molybdenum cofactors.

Journal of Biological Chemistry, 1992
crassa, demonstrated that the inactive apoprotein of nitrate reductase in extracts of the mutant could be reconstituted by the addition of denatured preparations of purified molybdoenzymes from animal, fungal, or bacterial origin. This crucial finding showed that mol- ybdoenzymes contain a dissociable entity fitting the description of a cofactor and ...

Applications of QSPR and Machine Learning in Molecular Photonics

Advanced Optical Materials, Volume 13, Issue 33, November 25, 2025.
Quantitative structureproperty relationships (QSPR) and machine learning (ML) are transforming photochemistry by enabling pre‐synthetic screening of photoactive molecules. This review outlines advances in data‐driven discovery of optical materials and functional dyes, identifies effective descriptors and models for photophysical processes, and provides

An Allele of Glutamate Formiminotransferase Triggers 5‐Methyl‐Tetrahydrofolate‐to‐MeFox Conversion and Facilitates Folate Biofortification in Maize

Advanced Science, Volume 12, Issue 42, November 13, 2025.
This work demonstrates the distinct roles of the glutamate formiminotransferase (GFT) enzyme in plants. The GFT triggers the conversion of 5‐methyl‐tetrahydrofolate to MeFox in plants, a process distinct from its role as a formiminotransferase in mammals.
