Mass spectrometric peptide sequencing: Cyclochlorotine

Biological Mass Spectrometry, 1979
A potent toxin isolated from Penicillium islandicum Sopp was found to have the composition C24H31N5O7Cl2. Mass spectrometric investigation of a partial acid hydrolyzate showed that it has the structure of cyclochlorotine. The mass spectral characteristics of polyamino alcohol-related derivatives of peptides containing beta-phenylalanine, alpha-amino ...

Microfluidic Superheating for Peptide Sequence Elucidation

Analytical Chemistry, 2015
Herein, we introduce microfluidic superheating as a new method for peptide fragmentation prior to mass spectrometric analysis. The superheating conditions were found to be stable up to 240 °C for more than 30 min without elevated pressure or boiling of the aqueous sample. As proof of principle, we exposed the peptides ACTH1-10 and OVA257-264 to various

Sequence generation in prebiological peptide synthesis

Archives of Biochemistry and Biophysics, 1967
Abstract In contradistinction to the suggestion that peptide synthesis occurring nonenzymically on the primitive Earth would be a totally random event, evidence is presented that the interaction of any one given amino acid with another follows well-defined statistics based on the relative reactivity of each amino acid. The effects of environment, pH,

Polypeptide Helices in Hybrid Peptide Sequences

Journal of the American Chemical Society, 2005
A new class of polypeptide helices in hybrid sequences containing alpha-, beta-, and gamma-residues is described. The molecular conformations in crystals determined for the synthetic peptides Boc-Leu-Phe-Val-Aib-betaPhe-Leu-Phe-Val-OMe 1 (betaPhe: (S)-beta3-homophenylalanine) and Boc-Aib-Gpn-Aib-Gpn-OMe 2(Gpn: 1-(aminomethyl)cyclohexaneacetic acid ...

On the predictive recognition of signal peptide sequences

Virus Research, 1985
DNA sequence analysis of the short unique regions in the genomes of herpes simplex virus (HSV), types 1 and 2, has previously shown that within this region there are four genes, designated US2, US4, US5 and US7, whose functions are unknown but whose predicted amino sequences exhibit hydrophobic N-termini (D.J. McGeoch et al., 1985, J. Mol. Biol. 181, 1-

Peptimmunology: Immunogenic Peptides and Sequence Redundancy

Current Drug Discovery Technologies, 2005
Using short peptide fragments of proteins to elicit antibodies able to recognize the protein from which the peptide sequence was derived, is one of the main goals in immunotherapy today. Indeed, peptide-immunotherapy appears as an obliged way to obtain antibodies of predetermined specificity and exempt from the complications associated with whole cells/
