===Monellin (MNEI) at 1.15 resolution===

~~==Overview==~~

<!--

The ~~X-ray crystal structure of a single-chain monellin protein~~ (~~MNEI) has been determined~~ at 1.~~15 A resolution~~. ~~The model was refined to convergence employing anisotropic displacement parameters and riding H atoms to produce a final model with R(work) and R(free~~) ~~values of 0.132 and 0.162~~, ~~respectively. The crystal contains a single MNEI protein in~~ the ~~asymmetric unit and unusually lacks the dimer interface observed in all previous crystal structures of monellin and its single-chain derivatives~~. ~~The high resolution allowed a more detailed view of MNEI than previously possible, with 38 of the 96 residues modelled with alternative side~~-chain conformations, including four core residues Thr12, Cys41, Leu62 and Ile75. Four stably bound negative ions were also located, providing new insight into potential electrostatic interactions of MNEI with the largely negatively charged surface of the sweet taste receptor T1R2-~~T1R3.~~
