The absorption spectra of human red and green visual pigments have peak wavelengths, lambda max, that differ by 31 nm, yet the opsins differ in only 15 amino acids. Mutagenesis studies have demonstrated that seven of the 15 amino acids determine the spectral shift. We trained neural networks to predict the lambda max of any red/green chimeric protein. Seven mutants were excluded from the origin...


 One of the processed soybean products that is a good source protein tofu. for body because amount it contains and its high digestibility. Tofu was first made around 200 BC by one Chinese cooks who accidentally added nigari or salt solution to juice until clumping process occurred into solid. Since then, tofu as product has been accepted health Asians. The word comes from language, namely...

seed protein quality is an important topic in the production of soybean. the quality of soybean proteins is limited by anti-nutrient proteins and low levels of essential sulfur amino acids. in this study, protein content and solubility of six cultivars were evaluated and seed storage proteins were analyzed using sds-page and scanning densitometry. the results showed that seed storage protein ba...

The oncoprotein c-Myc plays an important role in cell proliferation, transformation, inhibition of differentiation and apoptosis. These functions most likely result from the transcription factor activity of c-Myc. As a heterodimer with Max, the c-Myc protein binds to the E-box sequence (CACGTG), which is also recognized by USF dimers. In order to test differences in target gene recognition of c...

In the context of comparative analysis of protein-protein interaction graphs, we use a graph-based formalism to detect the preservation of a given protein complex G in the protein-protein interaction graphH of another species with respect to (w.r.t.) orthologous proteins. Two problems are considered: the Exact-(μG, μH)-Matching problem and the Max-(μG, μH)-Matching problems, where μG (resp. μH)...

seed protein profiles of 47 accessions belonging to eleven species and four tribes of grain legumes were studied, by extracting the total proteins from ten single seeds in each accession and performing sds-polyacrylamide gel electrophoresis. all eleven species were clearly recognizable from their protein banding patterns, but only phaseolus vulgaris expressed high intraspecific variations, ...

Despite the fact that many different programs have been developed in the field of NMR-based structure determination, the 3D structure determination of a large protein is still very time consuming and needs a lot of manual intervention. Therefore, it is highly desired to automate as many of the steps "peak picking", "assignment", and "structure calculation" as possible in a self-consistent manne...
