متن کاملSynthesis of nocistatin C-terminal and it’s amide derivatives as an opioid peptide
A new biological active hexapeptide of C-terminal of nocistatin, contains Glu-Gln-Lys-Gln-Leu-Gln sequence was synthesized according to solid phase peptide synthesis on the surface of 2-chloro tritylchloride resin and using fmoc-protected amino acids in the presence of TBTU (O-(Benzotriazol-1-yl)-N,N,N',N'-tetramethyl uranium tetrafluoroborate) as a coupling reagent. Then, amidation of the C-te...

متن کاملAn amino-terminal peptide of beta-galactosidase. Its detection in crude extracts of wild type and nonsense mutants of Escherichia coli.
Analysis by the Sanger procedure of cyanogen bromide (BrCN)-treated @-galactosidase and reduced carboxymethylated fi-galactosidase indicated the presence of 23 peptides with 11 different NHt-terminal amino acids. Of two peptides containing NH&erminal threonine, one obtained after gel filtration was found to be threonylhomoserine. Threonylmethionine was shown to be the NHp-terminal sequence of ,...
متن کاملFAST ATOM BOMBARDMENT MASS SPECTROMETRY (FABMS) ANALYSIS OF AN N- TERMINAL - BLOCKED PEPTIDE
FABMS analysis of T-lb peptide before and after one cycle of Edman degradation indicated an unblocked N-terminal Thr residue for this tryptic peptide. In contrast , our data showed a molecular protonated ion, MH + for T- la peptide at 655 mass units (mu) which is 42 mu higher than the MH ion of T- 1b peptide. In addition, T- la peptide was not amenable to one cycle of manual Edman degrada...
