Unveiling a VEGF-mimetic peptide sequence in the IQGAP1 protein.

Molecular Biosystems, 2017
The ability to modulate angiogenesis by chemical tools has several important applications in different scientific fields. With the perspective of finding novel proangiogenic molecules, we searched peptide sequences with a chemical profile similar to that

Peptide-mediated synthesis of gold nanoparticles: effects of peptide sequence and nature of binding on physicochemical properties.

Nanoscale, 2014
Biomimetic nanotechnologies that use peptides to guide the growth and assembly of nanostructures offer new avenues for the creation of functional nanomaterials and manipulation of their physicochemical properties. However, the impacts of peptide sequence

Programming pH-triggered self-assembly transitions via isomerization of peptide sequence.

Langmuir, 2014
While the ordering of amino acids in proteins and peptide-based materials is known to affect their folding patterns and supramolecular architectures, tailoring self-assembly behavior in stimuli responsive peptides by isomerizing a peptide sequence has ...

Sequence‐assisted peptide synthesis (SAPS)

The Journal of Peptide Research, 1998
Abstract:In solid‐phase peptide synthesis (SPPS) the growing peptide chain may undergo chain aggregation which can cause serious synthetic problems. A number of investigations concerning this problem have been reported in the chemical literature. During a study of such “difficult sequences” using the Fmoc‐protection strategy, we have observed that ...

Determination of the optimal cell-penetrating peptide sequence for intestinal insulin delivery based on molecular orbital analysis with self-organizing maps.

Journal of Pharmacy and Science, 2013
Our recent work has shown that the intestinal absorption of insulin can be improved significantly by coadministration of cell-penetrating peptides (CPPs), especially penetratin.

Peptide sequencing by metastable mapping

Organic Mass Spectrometry, 1983
AbstractThe amino acid sequence of three simple peptides has been determined by the technique of metastable mapping. The products of decompositions in the first field free region of a forward geometry double focussing mass spectrometer are studied by decreasing the electric sector field between scans of the magnetic field.
