Addtional InformationFUNCTION:Plays a role in the defense of the germinating seed against micro-organisms, by inhibiting the growth of a range of filamentous fungi and bacteria, especially Gram-positive bacteria.Not cytotoxic for cultured human cells and are the smallest known plant-derived antimicrobial peptides. Peptide IB-AMP4 has a higher antifungal activity than IB-AMP1.DEVELOPMENTAL STAGE:Highly expressed in dry mature seed and by the stages 2-5 of developing seed. The peptide IB-AMP1 is also detected at early stages of germination (24 hours and 48 hours postgermination).DOMAIN:Contains repeated alternating basic mature peptide and acidic propeptide domains.PTM:The N-terminal of all peptides are blocked.PTM:The 4 cysteine residues of all peptides are involved in intrachain disulfide bonds.MASS SPECTROMETRY:Mass=2536.6; Method=Electrospray; Range=55-74; Source=PubMed:9305910;MASS SPECTROMETRY:Mass=2464.6; Method=Electrospray; Range=103- 122; Source=PubMed:9305910;MASS SPECTROMETRY:Mass=2527.4; Method=Electrospray; Range=233- 252; Source=PubMed:9305910;MASS SPECTROMETRY:Mass=2522.6; Method=Electrospray; Range=279- 298; Source=PubMed:9305910;
