Discovery and characterization of hevein-like peptides from American ginseng

Hevein-Like Peptides (HLPs) are one of the many categories under plant Cysteine-Rich Peptides (CRPs). CRPs possess abundant cysteine and unique multiple disulfide bridges, which confer high thermostable properties. As such, they are touted as potential active ingredients in biotherapeutics. However,...
