설명

Amino Acid Sequence

Cys-Asn-Cys-Lys-Ala-Pro-Glu-Thr-Ala-Leu-Cys-Ala-Arg-Arg-Cys-Gln-Gln-His-NH2 [Disulfide Bridges: 1-11, 3-15]

일반 설명

Apamin, a bee venom is a polypeptide, that is made of 18 amino acids with two disulfide bridges.

애플리케이션

Apamin has been used in microbiological assays for the determination of antimicrobial activity of synthetic apamin and as a standard for MALDI (matrix-assisted laser desorption/ionization matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and electrospray ionisation mass spectrometry (ESI-MS) analysis.

생화학적/생리학적 작용

Apamin is a neurotoxin which can pass the blood-brain barrier. In human, it might cause peripheral nerve dysfunction, mainly seen after bee stings.

The only polypeptide neurotoxin that is known to pass the blood-brain barrier. Blocks ATP-type Ca⁺²-activated K⁺ channels.
