Structure of the C123S mutant of dienelactone hydrolase (DLH) bound with the PMS moiety of the protease inhibitor phenylmethylsulfonyl fluoride (PMSF)

A. Robinson, K. J. Edwards, P. D. Carr, J. D. Barton, G. D. Ewart and D. L. Ollis

Synopsis: The structure of the DLH (C123S) with PMS bound indicates that the reason the enzyme is able to catalyse a wide range of dissimilar substrates is a consequence of its capacity to undergo a coordinated restructuring of the active site and associated regions of the molecule without compromising the stability of its tertiary fold.

Structures of recombinant native and E202Q mutant human acetylcholinesterase complexed with the snake-venom toxin fasciculin-II

G. Kryger, M. Harel, K. Giles, L. Toker, B. Velan, A. Lazar, C. Kronman, D. Barak, N. Ariel, A. Shafferman, I. Silman and J. L. Sussman

Synopsis: The structures of recombinant wild-type human acetylcholinesterase and of its E202Q mutant, as complexes with fasciculin-II, a `three-finger' snake neurotoxin, have been determined to 2.8 and 2.7 Å resolution, respectively. The overall structures of these complexes are similar to those of the Torpedo and mouse enzymes with fasciculin-II. Comparison of the wild-type and the mutant structures shows that removal of the charged group from the protein core, and its substitution by a neutral isosteric moiety, does not disrupt the functional architecture of the active center.
