Tryptophan 118-128 solute carrier family 26 member 8 Homo sapiens 85-92 10896952-4 2000 NMR spectroscopy and molecular modeling show that the effect of Trp(2)-Tat(1-9) could not be explained by significant alterations in the backbone structure and suggest that tryptophan enters favorable interactions with DP IV. Tryptophan 64-67 solute carrier family 26 member 8 Homo sapiens 71-78 10896952-4 2000 NMR spectroscopy and molecular modeling show that the effect of Trp(2)-Tat(1-9) could not be explained by significant alterations in the backbone structure and suggest that tryptophan enters favorable interactions with DP IV. Tryptophan 173-183 solute carrier family 26 member 8 Homo sapiens 71-78
