Amino acids were immobilised by attaching them via a carbamate linker to Wang resin. These intermediates were converted to 1-(1,3-benzoxazol-2-yl)alkanamines over three steps, followed by coupling with 4-alkyl-6-chloro-1,3,5-triazine-2-amines to furnish the desired N-[1-(1,3-benzoxazol-2-yl)alkyl]-6-alkyl-1,3,5-triazine-2,4-diamines. Physico-chemical property profiles were used to support design and development of a combinatorial library. The synthetic methodology ...

The biosynthesis of the FeMo cofactor (FeMoco) of Azotobacter vinelandii nitrogenase presumably starts with the production of its Fe/S core by NifB (the nifB gene product). This core is subsequently processed on the alpha2beta2 tetrameric NifEN complex (formed by the nifE and nifN gene products). In this article, we identify ...
