Yeast ribosomal protein L41 is dispensable in the yeast. Its absence had no effect on polyphenylalanine synthesis activity, and a limited effect on growth, translational accuracy, or the resistance toward the antibiotic paromomycin. Removal of L41 did not affect the 60:40 S ratio, but it reduced the amount of 80 S, suggesting that L41 is involved in(More)
Variation of seed α-amylase inhibitors was investigated in 1 154 cultivated and 726 non-cultivated (wild and weedy) accessions of the common bean, Phaseolus vulgaris L. Four α-amylase inhibitor types were recognized based on the inhibtion by seed extracts of the activities of porcine pancreatic α-amylase and larval α-amylase and larval α-amylase of the(More)
The inheritance of seed α-amylase inhibitor in the common bean and the genetic relationships among the variants and six arcelin variants in the common bean were investigated by crossing between accessions containing different αAI and arcelin variants. All seed proteins in parental, F1 and F2 seeds from the crosses were examined by Western-blot analysis. All(More)
Two genes encoding ribosomal protein YL41 were cloned from Saccharomyces cerevisiae chromosomal DNA. Both genes contain an uniterrupted region of only 75 nucleotides coding for a protein of 3.3 kD. Within the coding regions the nucleotide sequences are virtually identical, whereas in both the 5′-and 3′-flanking regions the two genes differ significantly(More)
Recently, a concept called “Double Integrity” becomes more important because the cleavage fracture initiation likely occurs in severer environment and extremely thick steels. However, there are no valid explanation of the brittle crack propagation and arrest behavior in steel plates. The authors developed a numerical model to predict the crack(More)
Various three-dimensional structures have been created on a nanometer scale using the self-assembly of DNA molecules. However, ordinary DNA structures breakdown readily because of their flexibility. In addition, it is difficult to control them by inputs from environments. Here, we construct robust and photocontrollable DNA capsules using azobenzenes. This(More)
Rubrobacter radiotolerans is the most radio-resistant eubacterium without spore-formation in the life cycle, and its D(37) is 16,000 Gy against gamma-rays. To understand the molecular mechanism of the high radio-resistance, we purified and characterized superoxide dismutase (SOD) of this organism as enzymatic radical scavenger, and then analyzed its genetic(More)
