In this article, an approach has been developed for the analysis of some small peptides with similar pI values by CE-ESI-MS based on the online concentration strategy of dynamic pH junction. The factors affected on the separation, detection and online

An innovative technique to investigate the intermediates involved in the biosynthesis of the lipoheptapeptide surfactin from Bacillus subtilis OKB105 combining whole-cell matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) with targeted generation of knock-out mutants was demonstrated. This method allows efficient

Porcine pepsin proteolysis of the hexapeptide Leu-Ser-p-nitro-Phe-Nle-Ala-Leu-OMe (where OMe = methoxy and Nle = norleucine) in the presence of dipeptide Leu-Leu synthesizes a new hexapeptide Leu-Ser-p-nitro-Phe-Leu-Leu. Contrary to transpeptidation kinetics of other proteases, which depend upon an acyl-enzyme intermediate, the

A [FeFe]-hydrogenase model compound (µ-S(CH(2))(3)S)Fe(2)(CO)(4)(PMe(3))(2) [1] has been encapsulated in a low molecular weight (LMW) hydrogelator (Fmoc-Leu-Leu). Linear infrared absorption spectroscopy, gel melting and ultrafast time-resolved infrared spectroscopy experiments reveal significant contrasts in chemical environment and photochemistry between the encapsulated
