Germans link allergies to gene and skin protein

Munich - German scientists Wednesday linked allergy illnesses including dermatitis, hay fever and asthma to a gene in 8 per cent of European populations that deprives them of an essential skin protein. A study of 3,000 Munich schoolchildren produced the proof that a lack of the protein filaggrin, found in skin cells, is associated with skin allergies. The study tracked down variants of the gene that produces the protein.

Deconstructing Green Fluorescent Protein

Green fluorescent protein (GFP) has been reassembled from two pieces, a large fragment 214 amino acids in length that is produced recombinantly (GFP 1−10) and a short synthetic peptide corresponding to the 11th stave of the β-barrel that is 16 amino acids long (synthetic GFP 11), following a system developed by Waldo and co-workers (Cabantous, S.; et al. Nat. Biotechnol. 2005, 23, 102−7) as an in vivo probe for protein association and folding. We demonstrate that the reassembled protein has identical absorption and excited-state proton transfer dynamics as a whole protein of the identical sequence. We show that the reassembled protein can be taken apart and the peptide replaced with a different synthetic peptide designed to perturb the chromophore absorption.

Native Conformation at Specific Residues in Recombinant Inclusion Body Protein in Whole Cells Determined with Solid-State NMR Spectroscopy

Inclusion bodies are insoluble aggregates that are formed by bacteria to store excess recombinant protein produced during expression. The structure of the protein in inclusion bodies is poorly understood but it has been hypothesized that the protein may form misfolded β sheet aggregates. This paper presents an isotopic labeling and solid-state nuclear magnetic resonance approach to determine the secondary structure of individual residues within a recombinant influenza virus “FHA2” protein in inclusion bodies. The inclusion bodies were studied either in the context of the unlysed hydrated E. coli cells or in the hydrated pellet formed from centrifugation of the material insoluble in the cell lysate. The native structure of FHA2 is predominantly helical and native helical structure was also observed for several specific residues in the

Protein folding: terahertz absorption spectroscopy detects changes in protein-water network

(Nanowerk News) Water is no passive spectator of biological processes; it is an active participant. Protein folding is thus a self-organized process in which the actions of the solvent play a key role. So far, the emphasis in studies of protein folding processes has been on observation of the protein backbone and its side chains.

Penn Study Finds Way to Prevent Protein Clumping Characteristic of Parkinson's Disease

Researchers have identified a protein from a most unlikely source--baker's yeast--that might protect against Parkinson's disease. By introducing the yeast protein Hsp104 into animal models of Parkinson's disease, researchers prevented protein clumping that leads to nerve cell death, characteristic of the disorder. Full story
