英文摘要 | From the venom of scorpion Buthus martensii Karsch, a short peptide (BmPO1, 29 amino acid resi-dues) was isolated and characterized as previously reported (Lebren, ft. IL, a at. (1997) Eur. J. Biochem. 245,457-464). It was shown to reduce 33% outward K~+ channel (hippocampal neurons) currents at 10 μM. The solution structure of BmPO1 was determined by 2D 1~H NMR spectroscopy. The NOEs, coupling constants, and H-D exchange obtained from NMR spectroscopy were used in structural calculations. The conformation of BmPO1 is composed of a short a-helix (Cys 3-Thr 12) and a two-stranded antiparallel β-sheet (Ala 15-Asp 20 and Lys 23-Pro 28). There are three disuffide bridges (Cys 3-Cys 19, Cys 6-Cys 24 and Cys 10-Cys 26) connecting theα-helix and β-sheet. Asp 20 to Lys 23 form a type II turn linking the two strands. Structural and electrostatic potential comparison be-tween BmPO1 and its analogues are also presented. |
