Plant nonspecific lipid transfer proteins (nsLTPs) are characterized by their ability to bind a broad range of hydrophobic ligands in vitro. Their biological function has not yet been elucidated, but they could play a major role in plant defense to physical and biological stress. An nsLTP was isolated from Amaranthus hypochondriacus seeds and purified by gel filtration and reversed-phase high-performance liquid chromatography techniques. The molecular mass of the protein as determined by mass spectrometry is 9747.29 Da. Data from amino acid sequence, circular dichroism and binding/displacement of a fluorescent lipid revealed that it belongs to the nsLTP1 family. The protein shows the alpha-helical secondary structure typical for plant nsLTPs 1 and shares 40 to 57% sequence identity with nsLTPs 1 from other plant species and 100% identity with an nsLTP1 from Amaranthus caudatus. A model structure of the protein in complex with stearate based on known structures of maize and rice nsLTPs 1 suggests a protein fold complexed with lipids closely related to that of maize nsLTP1.
