We investigated the conformations of peptides that encompass the B helix or C helix region formed in the molten globule of bovine ƒ¿-lactalbumin to get information on the molecular mechanism that stabilizes the molten globule. The CD spectra show that the isolated B and C helices are intrinsically unstable. The chemical shifts, NOE connectivities, and CD spectrum indicate that no helical struct...

We have previously isolated a developmentally regulated novel gene, priA, from the basidiomycete Lentinus edodes. The deduced PRIA protein contains the two set of motifs similar to a 'zinc finger' typified by transcription factor TFIIIA and the motif of a 'zinc cluster' observed in metallothioneins. It also contains a hydrophobic N-terminal sequence. Here Escherichia coli cells producing PRIA w...

the objectives of the present study were to evaluate spring wheat recombinant inbred lines (rils) of diverse origin by estimating genetic parameters viz., variability, character association, cluster analysis, and principal component analysis (pca) for spot blotch resistance and yield components at bhu agricultural research farm during 2010-2011. grain yield per plot was significantly and positi...

All chlorophyll (Chl)-binding proteins constituting the photosynthetic apparatus of both prokaryotes and eukaryotes possess hydrophobic domains, corresponding to membrane-spanning alpha-helices (MSHs). Hydrophobic cluster analysis of representative members of the different Chl protein superfamilies revealed that all Chl proteins except the five-helix reaction center II proteins and the small su...

Varicella-zoster virus open reading frame 10 (ORF10) protein, the homolog of the herpes simplex virus protein VP16, can transactivate immediate-early promoters from both viruses. A protein sequence comparison procedure termed hydrophobic cluster analysis was used to identify a motif centered at Phe-28, near the amino terminus of ORF10, that strongly resembles the sequence of the activating doma...

the species of dioscorea (yam) are regarded as a staple food crop for millions of people in the tropical and subtropical regions of the world. it is regarded as an important food crop next to cereals and grains due to high yield storage of carbohydrates. economically, only few species are recognized for cultivation from agricultural point of view, in spite of its large species diversity. the sp...

seeds of 200 accessions of alfalfa (medicago sativa l.) were provided from iraniannatural resource gene bank and were sown as drilled plot using alpha designs/unreplicatedwith 2 repeated entries within all of 10 blocks under dry land farming system in agriculturalresearch center of hamadan, iran during 2009 to 2010. the data were collected and analyzedfor plant height, stem number, leaf stem ra...

with a hydrophobic cluster of Tyr-59, Ile-60 and Leu-63 on one surface. It is this hydrophobic cluster that we suggest is being mimicked by the tryptophanyl-tryptophan groups as illustrated in Fig. 1. We also propose that the hydrophobic cluster in C3a represents a secondary binding site on the molecule, and it is a cooperative interaction on the receptor between the hydrophobic and effector si...
