Isolation and characterization of crosslinked peptides from elastin

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1973
Abstract 1. 1. Fractionation of a reduced elastin digest resulted in the isolation of peptide fractions enriched in crosslinking amino acids. All fractions exhibited a high content of alanine residues. 2. 2. Further chromatography of fractions containing the aldol condensation product led to the purification of four peptides.

Immunology of elastin: study of anti-elastin peptide antibodies by DOT immunobinding assay

Immunology Letters, 1987
In order to further investigate the role of the immune system in the arteriosclerotic process, we investigated the anti-elastin peptide antibodies (AEAb) of the IgG and IgM types by DOT immunobinding assay in the sera of patients suffering from various arteriosclerotic diseases. In total 232 control and pathological sera were studied.

A peptide carrier for the delivery of elastin into fibroblast cells

International Journal of Dermatology, 2012
AbstractBackground  Transmembrane delivery of active peptides and proteins, including skin delivery of cosmeceutical proteins such as collagen and elastin, has been a challenging issue. Amphipathic cell‐penetrating peptides (CPPs) have been proposed as carrier peptides to mediate cellular uptake of proteins without covalent binding.Materials and ...

Effect of Peptide Sequence on the LCST-Like Transition of Elastin-Like Peptides and Elastin-Like Peptide–Collagen-Like Peptide Conjugates: Simulations and Experiments

Biomacromolecules, 2019
Elastin-like polypeptides (ELPs) are thermoresponsive biopolymers that undergo an LCST-like phase transition in aqueous solutions. The temperature of this LCST-like transition, Tt , can be tuned by varying the number of repeat units in the ELP, sequence and composition of the repeat units, the solution conditions, and via conjugation to other ...

Solid-State NMR Studies of Elastin and Elastin Peptides

2007
The skin and blood vessels of a vertebrate have a uniquely resilient and elastic quality to them. These properties are traced to elastin, the principal protein component of the fibers that comprise a large portion of these elastic tissues. Numerous reviews have been written on the biology and chemistry of this unique protein [1–3]. Briefly, the elastin

Binding of some metastatic tumor cell lines to fibrous elastin and elastin peptides

International Journal of Cancer, 1993
AbstractRecent suggestions that tumor‐cell targeting of elastin‐rich tissues (e.g., lung) correlates with the presence of surface elastin receptors have been investigated. Receptors for insoluble (fibrous) elastin and for soluble elastin peptides have been implemented in these correlations.

[Elastin and arteriosclerosis: determination and characterization of elastin peptides in blood].

Comptes rendus des seances de la Societe de biologie et de ses filiales, 1993
During pathologies such as arteriosclerosis and emphysema, degradation of elastin by elastases occurs and elastin peptides are produced. In order to evaluate elastin degradation, measurements of elastin peptide concentration in human blood were carried out.

Circular dichroism studies of an elastin crosslinked peptide

Biopolymers, 1976
AbstractCircular dichroic studies of a desmosine crosslinked peptide reveal a hitherto undescribed elastin spectrum possessing a weak negative band at 230–235 nm, a weak positive band at 215 nm, and a maximum negative band at 190 nm. The spectrum is sensitive to both pH and temperature displaying increased ellipticity of the 215‐nm band at acidic pH ...

Characterisation of human lung elastin-derived peptides

Clinical Biochemistry, 1993
The enzymatic breakdown of human lung elastin by leukocyte elastase precedes the development of pulmonary emphysema, and releases elastin-derived peptides (EDPs) into the circulation. While raised levels of EDPs measured by enzyme-linked immunosorbent assay (ELISA) have been proposed as a possible marker for early detection of emphysema, average normal
