Proline 85-92 elastin Homo sapiens 121-128 17917856-1 2007 Extensive hydrogen bonding of dyes to connective tissue fibers is made possible by the high content of the amino acids proline and glycine in elastin and collagens. Proline 119-126 elastin Homo sapiens 142-149 16366565-0 2005 A stereoelectronic effect on turn formation due to proline substitution in elastin-mimetic polypeptides. Proline 51-58 elastin Homo sapiens 75-82 16366565-4 2005 Calorimetric and spectroscopic investigations of these three polypeptides indicate that the incorporation of the substituted proline residues had a dramatic effect upon the self-assembly of the corresponding elastin peptide. Proline 125-132 elastin Homo sapiens 208-215 16366565-6 2005 These results suggest that stereoelectronic effects could either enhance or hinder the self-assembly of elastin-mimetic polypeptides, depending on the influence of the proline analogue on the energetics of the beta-turn conformation that develops within the pentapeptide structural repeats above the phase transition. Proline 168-175 elastin Homo sapiens 104-111 16366565-8 2005 The results of the these calculations suggested a similar outcome to the experimental data for the elastin-mimetic polypeptides, in that type II beta-turn structures were stabilized for peptide segments containing (2S,4R)-fluoroproline and destabilized for segments containing (2S,4S)-fluoroproline relative to the canonical proline residue. Proline 228-235 elastin Homo sapiens 99-106 17098192-4 2006 The analysis of diverse sequences, including those of elastin, amyloids, spider silks, wheat gluten, and insect resilin, reveals a threshold in proline and glycine composition above which amyloid formation is impeded and elastomeric properties become apparent. Proline 144-151 elastin Homo sapiens 54-61 14625282-12 2004 This view is supported by recent studies of recombinant elastin polypeptides with systematic proline substitutions. Proline 93-100 elastin Homo sapiens 56-63 12031628-2 2002 beta-spirals using canonical proline-nucleated beta-turns in diverse proteins allow for vital functions including structural (mucin and amelogenin), respiratory (elastin), muscular (titin), and that of genetic expression (RNA polymerase II). Proline 29-36 elastin Homo sapiens 162-169 14606895-1 2003 The concentration dependence of the pressure- and temperature-induced cloud point transition (Pc and Tc, respectively) of aqueous solutions of an elastin-like polypeptide with a repeating pentapeptide Val-Pro-Gly-Ile-Gly sequence (MGLDGSMG(VPGIG)40VPLE) was investigated by using apparent light scattering, differential scanning calorimetry, and circular dichroism methods. Proline 205-208 elastin Homo sapiens 146-153 11911775-5 2002 It has been suggested that these hydrophobic domains, predominantly containing glycine, proline, leucine and valine, often occurring in tandemly repeated sequences, are responsible for the ability of elastin to align monomeric chains for covalent cross-linking. Proline 88-95 elastin Homo sapiens 200-207 10825173-3 2000 The tropoelastin-binding site was localized to a region beginning at the glycine-rich and proline-rich regions of fibrillin-2 and fibrillin-1, respectively, and continuing through the second 8-cysteine domain. Proline 90-97 elastin Homo sapiens 4-16 12785105-2 2002 Its soluble precursor (tropoelastin) has two major types of alternating domains: (1) hydrophilic cross-linked domains rich in Lys and Ala and (2) hydrophobic domains (responsible for elasticity) rich in Val, Pro, and Gly, which often occur in repeats of VPGVG or VGGVG. Proline 208-211 elastin Homo sapiens 23-35 11723825-1 2001 Elastin is the main protein of elastic fibers and confers the property of elastic recoil to the tissues such as arteries, lung, elastic cartilage,... Elastin synthesis goes through several steps: gene transcription, alternative splicing of pre-mRNA, mRNA translation, hydroxylation of some proline residues of the newly synthesized protein-tropoelastin-, association of with a 67 kDa chaperone protein, secretion of tropoelastin molecules in the extracellular space, and their deposition on the microfibrillar scaffold which contains fibrillin 1, fibrillin 2, MAGP 1 and MAGP 2,.... After the synthesis of cross-links-lysinonorleucine, desmosine, isodesmosine-, elastin becomes insoluble and elastic.

Proline 290-297 elastin Homo sapiens 150-157 11727705-5 2001 It is particularly true for human tropoelastin, because its sequence is rich in glycines and prolines, and these residues are frequently met in beta-turns (a beta-turn is made of four consecutive residues which are stabilized by an hydrogen bond). Proline 93-101 elastin Homo sapiens 34-46 2386811-9 1990 We propose that in the repeating sequences of elastin an equilibrium exists between a gamma-turn structure and a beta-turn structure in the Pro-Gly segment resulting in a structure that combines flexibility with strong conformational preferences. Proline 140-143 elastin Homo sapiens 46-53 1742165-1 1991 Poly(X-Gly-Gly), simple structural models for the hydrophobic, proline-devoid, regions of elastin, have been synthesized and studied by circular dichroism and NMR spectroscopies.

Proline 60-63 elastin Homo sapiens 103-110 6150137-6 1984 Elastin is composed largely of glycine, proline, and other hydrophobic residues and contains multiple lysine-derived cross-links, such as the desmosines, which link the individual polypeptide chains into a rubber-like network. Proline 40-47 elastin Homo sapiens 0-7 7104383-8 1982 The change in elastin concentration was accompanied by high hydroxyproline/proline or hydroxylysine/lysine ratios which indicates that the proteins of the aneurysmatic aortic wall contained more collagen than the proteins of the control aortic wall. Proline 67-74 elastin Homo sapiens 14-21 31278967-9 2019 Pro, Gly and Ala were preferably found at P1-P4 and P2"-P4" in both tropoelastin and elastin.

Proline 124-127 elastin Homo sapiens 91-98 26110966-1 2015 The solubility-enhancing power of covalent attachment to solvent-swollen cross-linked resin supports was illustrated by syntheses of the highly aggregating elastin-derived 10-residue peptide sequence Pro-Gly-Val-Gly-Val-Pro-Gly-Val-Gly-Val using standard protocols for both Boc and Fmoc chemistry SPPS. Proline 200-204 elastin Homo sapiens 156-163 27180175-8 2016 The fact that the highest hydroxylation degrees of proline residues were found for elastin from the intervertebral disc and knowledge of elastin arrangement in this tissue suggest that hydroxylation plays a biomechanical role. Proline 51-58 elastin Homo sapiens 83-90 27180175-9 2016 Interestingly, a proline-rich domain of tropoelastin (domain 24), which contains several repeats of bioactive motifs, does not show any hydroxyproline residues in the mammals studied. Proline 17-24 elastin Homo sapiens 40-52 27311421-8 2016 With respect to the molecular-level structure, it was found that the proline hydroxylation degree differed between WBS and healthy elastin, while the tropoelastin isoform appeared to be the same.

Proline 0-7 elastin Homo sapiens 92-99 25924982-4 2015 However, the native sequence of hydrophobic elastin domain 30 is uncharacteristically proline-poor and, as an isolated polypeptide, is susceptible to formation of amyloid-like structures comprised of stacked beta-sheet. Proline 86-93 elastin Homo sapiens 44-51 26763595-3 2016 While structural disorder of hydrophobic sequences is controlled by a high proline and glycine residue composition, hydrophobic domain 30 of human tropoelastin is atypically proline-poor, and forms beta-sheet amyloid-like fibrils as an individual peptide.

Proline 10-17 elastin Homo sapiens 132-139 20947499-2 2010 The monomeric precursor, tropoelastin, is highly hydrophobic yet remains substantially disordered and flexible in solution, due in large part to a high combined threshold of proline and glycine residues within hydrophobic sequences. Proline 174-181 elastin Homo sapiens 25-37 20947499-3 2010 In fact, proline-poor elastin-like sequences are known to form amyloid-like fibrils, rich in beta-structure, from solution. Proline 9-16 elastin Homo sapiens 22-29 20947499-5 2010 However, a small number of hydrophobic domains near the C terminus of tropoelastin are substantially depleted of proline residues.
