The role of protein hydrophobicity in thionin-phospholipid interactions : A comparison of α1 and α2-purothionin adsorbed anionic phospholipid monolayers
The plant defence proteins α1- and α2-purothionin (Pth) are type 1 thionins from common wheat (Triticum aestivum). These highly homologous proteins possess characteristics common amongst antimicrobial peptides and proteins, that is, cationic charge, amphiphilicity and hydrophobicity. Both α1- and α2-Pth possess the same net charge, but differ in relative hydrophobicity as determined by C18 reverse
