The S-carboxymethyl derivative chains of crosslinked and noncrosslinked fibrins were prepared from purified human fibrinogen. For crosslinked fibrin, fibrinogen was clotted with thrombin in the presence of calcium and purified human factor XIII. For noncrosslinked fibrin, ethylenediaminetetraacetate was substituted for factor XIII and calcium. After reduction with dithiothrcitol and alkylation ...
We consider six different secondary structures of proteins and construct two types of Go-like off-lattice models: with the steric constraints and without. The basic aminoacid-aminoacid potential is Lennard Jones for the native contacts and a soft repulsion for the non-native contacts. The interactions are chosen to make the target secondary structure be the native state of the system. We provid...
Sandhoff disease (SD) is a lysosomal disorder caused by mutations in the HEXB gene. To date, 43 mutations of HEXB have been described, including 3 large deletions. Here, we have characterized 14 unrelated SD patients and developed a Multiplex Ligation-dependent Probe Amplification (MLPA) assay to investigate the presence of large HEXB deletions. Overall, we identified 16 alleles, 9 of which wer...
The entire nucleotide sequence of the Ad.2 EcoRI E fragment has been determined using the Maxam and Gilbert method. This sequence of 2222 bp, which maps between coordinate 83.4 and 89.7 contains information relative to the early 3 region and to the fiber gene. Altogether with fragment EcoRI D which has been recently sequenced, they cover the entire Early 3 region in which several mRNA were mapp...
Lipopurothionins are complexes of basic polypeptides and polar lipids found in petroleum ether extracts of wheat endosperm. Location of the structural genes for the protein moiety and of genes probably controlling the lipid moiety has been achieved by analysis of compensated nulli-tetrasomic and ditelosomic lines of Triticum aestivum L. cv. Chinese Spring, as well as of other genetic stocks. Th...
Proteins from halophilic organisms, which live in extreme saline conditions, have evolved to remain folded at very high ionic strengths. The surfaces of halophilic proteins show a biased amino acid composition with a high prevalence of aspartic and glutamic acids, a low frequency of lysine, and a high occurrence of amino acids with a low hydrophobic character. Using extensive mutational studies...
Infant formulas contain nutrients and bioactive ingredients designed to meet the nutrition requirements of infants. The majority infant are cow's milk (CM) based regular ones. Since CM is one most important allergen source, there specialized such as partially extensively hydrolyzed, aminoacid‐based for CM‐allergic In current study, attenuated total reflectance-Fourier transform infrared spectro...
