Structure characteristics of XYP1. (A) The cDNA sequence and amino acid sequence of XYP1. (B) Sequence alignment and physicochemical properties of XYP1 and its analogs. (C) Mass spectra of XYP1. The calculated molecular weight of XYP1 was 2901.64 Da and the measured molecular weight was 2900.643 Da. (D) Helical wheel projection diagrams of XYP1. The hydrophobic residues are presented in yellow color, positively charged hydrophilic residues blue, the noncharged polar residue purple, and negatively charged hydrophilic residue red. The circular dichroism spectra of XYP1: in PBS (pH 7.4) (E) and in the presence of 50% TFE or SDS (100 mmol L⁻¹) (F) at 25 °C.
