Abstract

A sweet protein monellin was originally isolated from the berries of the West African plant Dioscoreophyllum cumminsii. The studies for molecular interaction of different sweeteners with receptor as well as receptor binding model have been proposed previously. The high-resolution solution structure of single-chain monellin (SCM) has been determined to investigate structural origin of sweet taste by NMR spectroscopy and simulated annealing calculations.(omitted)
