Enantiomeric separation of chiral dipeptides by CE-ESI-MS employing a partial filling technique with chiral crown ether.

Shifei Xia et al.

Electrophoresis, 30(16), 2837-2844 (2009-08-06)

Enantiomer of chiral dipeptides were separated by CE-ESI-MS in a bare fused-silica capillary using (+)-(18-crown-6)-2,3,11,12-tetracarboxylic acid (18C6H4) as the chiral selector. As 18C6H4 is a kind of nonvolatile chiral selector, in order to prevent from 18C6H4 into the ion-source of

Synthesis and binding studies of two new macrocyclic receptors for the stereoselective recognition of dipeptides.

Ana Maria Castilla et al.

Beilstein journal of organic chemistry, 6, 5-5 (2010-05-21)

We present here the design, synthesis, and analysis of a series of receptors for peptide ligands inspired by the hydrogen-bonding pattern of protein β-sheets. The receptors themselves can be regarded as strands 1 and 3 of a three-stranded β-sheet, with

Chiral capillary electrophoresis-mass spectrometry: modes and applications.

Shahab A Shamsi

Electrophoresis, 23(22-23), 4036-4051 (2002-12-14)

A review is presented to highlight several approaches for coupling capillary electrophoresis (CE) and electrospray ionization-mass spectrometry (ESI-MS) for analysis of chiral compounds. A short discussion of commercially available CE-MS instruments and interface design is followed by a detail review

An algorithm to find minimum free-energy paths using umbrella integration.

Matthias U Bohner et al.

The Journal of chemical physics, 137(3), 034105-034105 (2012-07-27)

The calculation of free-energy barriers by umbrella sampling and many other methods is hampered by the necessity for an a priori choice of the reaction coordinate along which to sample. We avoid this problem by providing a method to search

Biochemical characterisation of the chlamydial MurF ligase, and possible sequence of the chlamydial peptidoglycan pentapeptide stem.

Delphine Patin et al.

Archives of microbiology, 194(6), 505-512 (2012-01-11)

Chlamydiaceae are obligate intracellular bacteria that do not synthesise detectable peptidoglycan although they possess an almost complete arsenal of genes encoding peptidoglycan biosynthetic activities. In this paper, the murF gene from Chlamydia trachomatis was shown to be capable of complementing
