Abstract
D-Monellin is a chemically synthesized protein composed of all D-amino acids. It has an amino-acid sequence identical to L-monellin, a natur al protein with potent sweetness. Two crystal forms of D-monellin were obtained. Both crystals were grown under conditions similiar to those used to crystallize natural L-monellin. Crystal form I has similar, b ut not identical, cell parameters to natural L-monellin and diffracts to 2.7 Angstrom resolution. Crystal form II is very different and diff racts to 1.7 Angstrom resolution using synchrotron radiation.
