    摘要: The invention provides a method for improving the texture of a food product by incorporating in the food product or a precursor of the food product a bioelastic polypeptide in an amount sufficient to increase the elasticity of the food product, the bioelastic polypeptide having tetrapeptide or pentapeptide repeating units or mixtures thereof and the repeating units existing in a conformation having a .beta.-turn. The invention also provides a method for binding a food product precursor by adding a bioelastic polypeptide in an amount sufficient to bind the food product precursor, the bioelastomer having tetrapeptide or pentapeptide repeating units or mixtures thereof and the repeating units existing in a conformation having a .beta.-turn. The present invention further provides a food adjunct containing a bioelastic polypeptide having tetrapeptide or pentapeptide repeating units or mixtures thereof where the repeating units exist in a conformation having a .beta.-turn, and an edible material suitable for human or animal consumption.

    摘要: The present invention relates to biologically active peptides with reduced toxicity and methods of preparing them. The peptides of the invention, which can be unsubstituted or N-terminal substituted have the formula: wherein X is a biologically active amphiphilic ion channel-forming peptide or protein, T is a lipophilic moiety or hydrogen, and W is T or hydrogen. Preferably T is: wherein R is a hydrocarbon (alkyl or aromatic or alkylaromatic) having at least 2 and no more than 10 carbon atoms. T is preferably an octanoyl group. The peptides and proteins of the invention have improved antimicrobial and anti-tumor biological activity while exhibiting reduced toxicity. A preferred method of reducing toxicity involves the formation of related methane sulfonate derivatives or analogues. Additionally, the compounds of the invention may be used to treat sepsis, septic shock, and lung infections, such as those occurring in cystic fibrosis.

    摘要: A C to T DNA variation at position 3365 in exon 5 of the human Asthma Associated Factor 1 (AAF1) produces the predicted amino acid substitution of a methionine for a threonine at codon 117 of AAF1. When this substitution occurs in both alleles in one individual, it is associated with less evidence of atopic allergy including asthma, fewer abnormal skin test responses, and a lower serum total IgE. Thus, applicant has identified the existence of a non-asthmatic, non-atopic phenotype characterized by methionine at codon 117 when it occurs in both AAF1 gene products in one individual.
