One possibility is that the MIDAS site serves to attach protein ligands through a mechanism involving participation of a glutamate or aspartate residue on the ligand in the coordination of a Mg 2+ion at the MIDAS site of midasin, in a manner similar to that by which the MIDAS site in integrin I-domains appears to mediate attachment of collagen through the glutamate in the GFOGER binding motif [ 36 ] . Interestingly, the related RGE ligand-binding motif [ 41 ] occurs in a conserved region of the midasin AAA-domain (yeast, residues 1835-1838), as well as in the AAA-domain of Mg chelatases [ 32 ] . The presence of this consensus binding motif in the AAA domain raises the possibility of the midasin molecule folding back onto itself, with the M-domain becoming attached to one face of the AAA domain and perhaps regulating access to its central chamber, in a manner analogous to that in which the 19S proteasome regulator, also an AAA protein, controls access to the central proteolytic chamber of the proteasome [ 42 ] .
A cDNA that encodes a hemagglutinin-tagged NPM3 protein was produced by PCR under the following conditions: 100 μl reactions with 1X Pfu buffer, 0.2 mM deoxyribonucleotides, 1 μM HA-F primer (5'-AAA GAA TTC AGC ATG TAC CCA TAC GAC GTC CCA GAC TAC GCC GCC GCC GGT ACT GCA GCT GCC-3'), 1 μM NPM3 -R2 primer (5'-AAA GAA TTC CTA GGG CCT GCC CCC CTG CTT TTT GGC AGG AAG GAT GGG-3'), 1 ng of human NPM3 cDNA insert, and 2.5 Units of recombinant Pfu DNA Polymerase.
For NRG1, the oligos used were HZ034, 5' TCG ACC AGC ATA TTA CTA CCC TTC GCA AAC TTT CAG GCA CTG TGC GGT ATT TCA CAC CG 3'; and HZ035, 5' GTA GTA CTG CTA ATG AGA AAA ACA CGG GTA TAC CGT CAA AGA TTG TAC TGA GAG TGC AC 3'.
The early evolutionary divergence of the different major branches of the AAA family makes it difficult to evaluate the phylogenetic relationships among them [ 45 ] . However, by restricting the analysis to residues in the more highly conserved regions of the AAA structure that interact directly with ATP, we have been able to improve the signal to noise ratio sufficiently to probe the phylogenetic relationship of midasin and dynein to representative members in other branches of the AAA family.
Every nucleic acid sequence necessarily has an associated GC content, but there need be no similarities in codon usage between different species with the same GC content (for instance, any specified GC content could be obtained by mixing AAA and GGG codons in different ratios).
