“…18) and Ag 3 N (Ref. 19) suggests that a Au 3 N stoichiometry is a good starting point for further investigation. Using DFT with first-principles pseudopotentials it is possible to directly compare the total energy for different Au 3 N crystal structures, including complex crystal structures with bases consisting of many Au 3 N units, and to identify the optimum lattice parameters for these structures.…”

Photoemission spectroscopy demonstrates the formation of a surface gold nitride upon irradiation of a Au͑110͒ surface with 500 eV nitrogen ions at room temperature. After irradiation two N1s peaks are observed at binding energies of 396.7± 0.2 eV and 397.7± 0.2 eV along with a broadening of the Au4d 5/2 line. Changes in valence-band spectra are also observed, including an additional density of states at 1.6 eV binding energy and new states at ϳ3.1 eV. Annealing experiments indicate that the two N1s lines are associated with nitrogen compounds of differing thermal stability, possibly due to the formation of more than one nitride phase. To further investigate the properties of gold nitride we have undertaken ab initio pseudopotential calculations on the most likely nitride stoichiometry, Au 3 N, and identified a novel triclinic crystal structure of a significantly lower energy than the anti-ReO 3 expected from a simple consideration of the periodic table, although the latter structure is also found to be stable. The triclinic structure is determined to be metallic, of importance to possible applications.

“…The first example is provided by Ag 3 N. This compound is extremely explosive at ambient pressure, 138 due to its susceptibility to decompose to the constituent elements. However, our GGA/PBE calculations show that hypothetical Ag 3 N might be stabilized by addition of atomic Xe with the concomitant formation of [Ag 3 Xe]N under elevated pressure.…”

Drug discovery often begins with the screening of large compound libraries to identify lead compounds. Recently, the enzymes involved in the biosynthesis of natural products have been investigated for their potential to generate new, diverse compound libraries. There have been several approaches toward this end, including altering the substrate specificities of the enzymes involved in natural product biosynthesis and engineering functional communication between enzymes from different biosynthetic pathways. While there exist assays to assess substrate specificity of enzymes involved in these pathways, there is no simple method for determining whether enzymes from different synthases will function cooperatively to generate the desired product(s). Herein we report a method which provides insight into both substrate specificity and compatibility of protein-protein interactions between the acyl carrier protein (ACP) and ketosynthase (KS) domains involved in fatty acid and polyketide biosynthesis. Our technique uses a one-pot chemoenzymatic method to generate post-translationally modified ACPs capable of covalently interacting with KS domains from different biosynthetic systems. The extent of interaction between ACPs and KSs from different systems is easily detected and quantified by a gel-based method. Our results are consistent with previous studies of substrate specificity and ACP-KS binding interactions and provide new insight into unnatural substrate and protein interactions.
