1124 + 41 was activated in the mutant construct, and the normal intron 9 acceptor site was used.
The resulting cations are best described as 1:1 adducts of a neutral ligand on a phosphadiazonium Lewis acceptor (1), and highlight the potential for electron-rich centres to behave as Lewis acids in spite of the presence of a lone pair of electrons at the acceptor site.
Botulinum toxin type A is known to block neuromuscular transmission by binding to acceptor sites on motor or sympathetic nerve terminals, entering the nerve terminals and inhibiting the release of acetylcholine.
We estimated H-bond interaction energies of the putative donor and acceptor sites on the natural AR ligand, DHT, and selected nonsteroidal analogues using the PM3 method to compute the energies of interaction with a single water molecule at each site; PM3 fully optimized conformations of the water-bound species were computed for this purpose.
