Synthesis of Fragments of the Peptide Component of Pseudobactin

Journal of Peptide Science, 1996
AbstractPseudobactin is a structurally complex and physiologically important siderophore (microbial iron chelator) from Pseudomonas putida‐ fluorescens. Various fragments of the unusual peptide component of pseudobactin listed below were prepared by solution‐phase peptide synthesis.L‐Lys· D‐threo‐β‐OH Asp· L‐Ala· D‐allo‐Thr· L‐AlaL‐Lys· D‐threo‐βOH Asp·

Studies on peptide fragments of prion proteins

2001
Publisher Summary The prion diseases are neurodegenerative disorders of humans and animals that are sporadic or inherited in origin and can be transmitted. Despite remarkable differences in phenotypic expression, these disorders share a similar pathogenic mechanism— that is, a post-translational modification of the prion protein from a normal ...

A global analysis of peptide fragmentation variability

PROTEOMICS, 2011
AbstractUnderstanding the fragmentation process in MS/MS experiments is vital when trying to validate the results of such experiments, and one way of improving our understanding is to analyze existing data. We here present our findings from an analysis of a large and diverse data set of MS/MS‐based peptide identifications, in which each peptide has ...

Peptide Fragmentation during Nanoelectrospray Ionization

Analytical Chemistry, 2010
Electrospray ionization (ESI) is considered a soft ionization method, and typically no peptide ion fragmentation is observed. Recently, it has been observed that intensive fragmentation of peptide ions can occur during nanoelectrospray (nanoESI) at special conditions, such as solutions containing high concentrations of salt and relatively low voltage ...

Proposed nomenclature for peptide ion fragmentation

International Journal of Mass Spectrometry, 2015
Abstract The multitude of fragmentation techniques available to modern tandem mass spectrometry introduces diversity in the types of product ions. An all-explicit nomenclature system for the product ions of peptide fragmentation is herein proposed for the sake of clarity and unambiguity.

Fragmentation induced in atmospheric pressure photoionization of peptides

Journal of Mass Spectrometry, 2006
AbstractIn this work, the fragmentation of peptides under atmospheric pressure photoionization conditions is investigated. Intensive fragmentations into b/y‐ and c‐sequence ions are reported. Abundance of these c‐ions appeared to be related to the quantity of dopant infused and to the disappearance of the doubly protonated peptide ion.

Peptide Fragment Intensity Statistical Modeling

Analytical Chemistry, 2007
We present new statistical models of peptide fragment peak intensities that achieve unprecedented accuracy, and we discuss their application to the problem of scoring in database searching or peptide de novo sequencing. The models, made available via open-source computer programs, are very general and can potentially improve any intensity-based scoring.
