Addtional InformationActive against Gram-positive (C. michiganensis) and Gram-negative (R. solanacearum) bacteria. Transgenic plants: Overexpression of snakin-1 gene enhances resistance to Rhizoctonia solani and Erwinia carotovora in transgenic potato plants (Mol Plant Pathol. 2008 May;9(3):329-38). Crystal structure has been sovled using Racemic Protein Crystallography. You can rotate, zoom, and view the 3D structure here in the PDB. There are also other structures in the PDB. The crystal structure reveals a unique protein fold with six disulfide crosslinks, presenting a distinct electrostatic surface that may target the protein to microbial cell surfaces (Yeung H et al., 2016).
