(a) 1H 1D spectrum of neotame; (b) STD signal resulting from binding of neotame to the VFTM of T1R2. Only resonances at lower frequencies from the water signal are shown; these signals arise from binding of neotame to the purified amino terminal domain of the hT1R2 subunit. Data were processed by NMRPipe software, and subtraction was performed by Newton (in-house) software in the frequency domain.
