He worked instead on other terrorist schemes, such as buying four tons of ammonium nitrate for bombs to be planted on cargo planes flying to the United States.
Of similar importance would be issues related to the relative toxicity of sulfate particles, nitrate particles, and primary combustion particles from various sources.
Under anaerobic conditions, dmsA expression is repressed approximately 10-fold by NarL when nitrate is present [ 4 ] . Although three putative NarL sites have been proposed based on their similarity to a NarL consensus recognition sequence, TACYYMT (Y = C or T, M = A or C) [ 24 25 26 ] , no in vivo or in vitro information is available regarding the location of the NarL site(s) within the dmsA regulatory region.
The residues in the MIDAS motifs lie on three closely apposed loops located on the upper edge of the β-sheet, where they form the metal-binding site, with oxygen atoms in the aspartate, serine and threonine residues coordinating the metal ion [ 9 ] . In integrin α2β1, which is a collagen receptor, the metal-binding site also binds the collagen ligand through the conserved glutamate in a GFOGER motif (O = hydroxyproline) completing the coordination sphere of the metal [ 28 ] . In vivo, the binding of collagen at this site appears to be regulated through a conformational shift in which the loops forming the MIDAS site change from a closed to an open conformation [ 29 30 31 ] . Other proteins containing a domain with all three MIDAS motifs include the D-subunit of magnesium chelatase [ 32 ] , Ca-activated chloride-channel protein [ 33 34 ] , nitrate reductase (accession AAC79447), and the D subunit of nitric oxide reductase (accession AAC45374).
Earlier studies have shown that DAP, in DNA fragments, can widen the minor groove, as detected by reactivity towards uranyl nitrate or susceptibility to Dnase cleavage [ 29 ] , and can relieve compressions in the minor groove associated with A-tracts [ 30 ] . In contrast, NMR and molecular modeling studies of an oligonucleotide duplex containing MeC have demonstrated that, while this duplex still has a B-DNA conformation, there are differences in the structural parameters and thermal stability relative to the unmodified duplex [ 31 ] . An earlier study also found, in two closely related octanucleotide duplexes, that although the methylated duplexes retained their B-DNA conformation, different structural and thermal stability effects were seen [ 32 ] . Although these studies have been carried out with DNA-DNA and not DNA-RNA duplexes, it is possible that MeC substitution may have different structural consequences than DAP substitution.
