== Publication Abstract from PubMed ==
 +
The crystal structure of mouse acetylcholinesterase at 2.9-A resolution reveals a tetrameric assembly of subunits with an antiparallel alignment of two canonical homodimers assembled through four-helix bundles. In the tetramer, a short Omega loop, composed of a cluster of hydrophobic residues conserved in mammalian acetylcholinesterases along with flanking alpha-helices, associates with the peripheral anionic site of the facing subunit and sterically occludes the entrance of the gorge leading to the active center. The inverse loop-peripheral site interaction occurs within the second pair of subunits, but the peripheral sites on the two loop-donor subunits remain freely accessible to the solvent. The position and complementarity of the peripheral site-occluding loop mimic the characteristics of the central loop of the peptidic inhibitor fasciculin bound to mouse acetylcholinesterase. Tetrameric forms of cholinesterases are widely distributed in nature and predominate in mammalian brain. This structure reveals a likely mode of subunit arrangement and suggests that the peripheral site, located near the rim of the gorge, is a site for association of neighboring subunits or heterologous proteins with interactive surface loops.
