General Info

  • lamp_id:L01A000500
  • Name:DMS4_PHYSA
  • FullName:Dermaseptin-4
  • Source:Phyllomedusa sauvagei
  • Mass:2779.4 Da
  • Sequence Length:27 aa
  • Isoelectric Point:11.28
  • Activity:Antibacterial, Antifungal, Antiviral
  • Sequence
        ALWMTLLKKVLKAAAKALNAVLVGANA
  • Function:Possesses a potent antimicrobial activity against Gram-negative and Gram-positive bacteria, fungi, protozoa, and the enveloped herpes simplex virus type 1. Probably acts by disturbing membrane functions with its amphipathic structure. Binds to healthy erythrocytes (this binding is receptor independent), and has strong hemolytic activity. Does not bind to P.falciparum infected erythrocytes, but accumulates within the parasite. Kills the parasite, and only at high concentrations has an hemolytic activity on the host cell.
