Sequence-specific assignment of 1H-NMR resonance and determination of the secondary structure of Jingzhaotoxin-I.
Jingzhaotoxin-I (JZTX-I) purified from the venom of the spider Chilobrachys jingzhao is a novel neurotoxin preferentially inhibiting cardiac sodium channel inactivation by binding to receptor site 3. The structure of this toxin in aqueous solution was investigated using 2-D 1H-NMR techniques. The complete sequence-specific assignments of proton resonance in the 1H-NMR spectra of JZTX-I were obt...
متن کاملSequence-specific 1H NMR assignments and secondary structure of the streptococcal protein G B2-domain.
Two-dimensional NMR spectroscopy has been used to obtain sequence-specific 1H NMR assignments for the IgG-binding B2-domain of streptococcal protein G. Secondary structure elements were identified from analysis of characteristic backbone-backbone NOE patterns and amide proton exchange data. The B2-domain contains a four-stranded beta-sheet region in which the two inner strands form a parallel b...
متن کاملSequence-specific 1H assignment and secondary structure of the bacteriocin AS-48 cyclic peptide.
The bacteriocin AS-48 is a cationic peptide (7149 Da) having a broad antimicrobial spectrum, encoded by the 68 kb conjugative plasmid pMB2 from Enterococcus faecalis S-48. It is a unique peptide since it has a cyclic structure, which is achieved by the formation of a tail-head peptide bond after ribosomal synthesis (Gálvez et al., 1989; Martínez-Bueno et al., 1994; Samyn et al., 1994). Prelimin...
متن کاملA 1H-NMR study of the solution conformation of secretin. Resonance assignment and secondary structure.
The solution conformation of the 27 residue polypeptide hormone secretin has been investigated by 1H-NMR spectroscopy under conditions where it adopts a fully ordered structure as judged by circular dichroism spectroscopy, namely in an aqueous solution of 40% (v/v) trifluoroethanol. Using a combination of two-dimensional NMR techniques the 1H-NMR spectrum of secretin is completely assigned and ...
متن کاملکلون کردن ژن ns-ltp (non-specific lipid-transfer protein) برنج با برچسب gst به داخل باکتری اشرشیا کلی
پروتئین های ناقل لیپید (ltps) گروهی از پروتئین ها با وزن ملکولی متوسط در نزد گیاهان هستند که دارای پتانسیل های کاربردی به ویژه در سیستم های رها سازی دارو می باشند. هدف از این تحقیق، کلون کردن ژن ltp2 مربوط به گیاه برنج(oryza sativa) در وکتور بیانی pgex-6p-2، در باکتری e.coli (top10) جهت تولید پروتئین به صورت متصل با gst می باشد. از آنجائیکه ژن ltp2 در گیاه برنج را فاقد اینترون است این ژن با کمک...
