Fig. 5.
Calculated 3-D structure of the thaumatin-like protein (TLP) from Nepenthes gracilis. The structure was suggested by the SWISSMODEL web server upon comparative modelling using a TLP from banana (Musa acuminate; Ban-TLP, 1Z3Q_A) as the homologous template structure. The model shows three domains (I, II and III): domain I which is a β-sandwich consisting of 11 β-sheets; domain II which contains one α-helix and one β-sheet; domain III which forms a hair-pin, built by two β-sheets.
