LITERATURE
E154C
-
purified preparations of mutant contain 0.1-0.4 atoms of Zn2+ per subunit and exhibit a constant catalytic Zn2+ centre activity of 1.19 per s, mutant does not require exogenous Zn2+ for stability. Mutant retains less than 1% of wild-type catalytic efficiency and displays similar primary and solvent deuterium effects as wild-type

-
mutation in hydrogen onding network, complete loss of activity and destabilization of protein into tetramers, dimers and monomers compared to only tetramers for wild-type
