Sphistin Synthetic Peptide (12-38, Fitc in N-Terminal-Fluorescently Labeled Peptide) is a truncated fragments of Sphistin Synthetic Peptide that shows potent antimicrobial activity.
Sphistin is a synthetic 38-amino acid H2A derived peptide from Scylla paramamosain. Sphistin Synthetic Peptide (12-38) shows a stronger activity with a much lower minimum inhibitory concentration (3 mM) against Staphylococcus aureus, Corynebacterium glutamicum, Micrococcus lysodeikticus Fleming, Bacillus subtilis, Pseudomonas fluorescens, Aeromonas hydrophila and A. sobria in comparison with the reported Sphistin. A leakage of intracellular content is described in E. coli treated with Sphistin Synthetic Peptide (12-38). Unlike Sphistin which mainly disrupts the membrane integrity, Sphistin Synthetic Peptide (12-38) could also combine the A. sobria genomic DNA with a minimum concentration of 6 mM and is located intracellularly in cells observed under confocal laser scanning microscope imaging[1].
In comparison with the control group of Oryzias melastigma injected with A. sobria alone, the group treated with a mixture of Synthetic Peptide (12-38) and A. sobria shows a higher survival rate 7 days post-injection. Furthermore, in a pretreatment assay at 6 h, a higher survival rate is observed in the group injected with the mixture of Synthetic Peptide (12-38) and A. sobria[1].
