Several Chlorella virus CVK2 proteins had chitosanase and/or chitinase activities. A gene coding for an ORF of 328 amino acids (aa) with a predicted molecular mass of 36,769 Da was cloned from the viral genome. The predicted amino acid sequence of an N'-portion (174 aa) of this gene product (vChta-1) showed 22 to 25% identity with various bacterial(More)
Using a halo assay with E. coli lysates expressing Chlorella virus CVK2 genes on a cosmid contig, two different algal-lytic activities against Chlorella strain NC64A cells were found to be encoded on the CVK2 genome. The gene for vAL-1, one of the two activities, encoded a 349-aa ORF, which was homologous to PBCV-1 A215L and CVN1 CL-2. The vAL-1 gene was(More)
VChti-1 chitinase encoded by the Chlorella virus CVK2 contained two catalytic domains belonging to family 18 glycosyl hydrolases. The first catalytic domain on a C-terminal-truncated derivative of vChti-1 generated exclusively chitobiose from chitotetraose, chitohexaose, and colloidal high-molecular mass chitin in the enzyme reaction, a typical(More)
Chlorella virus CVK2 particles contain several capsid proteins that are selectively released by treatment with 4 M urea. Seven of them (Vp52, Vp45, Vp41, Vp25, Vp20.5, Vp20, and Vp16.2) have been identified based on amino acid sequences at the N-terminus. Comparison of the amino acid sequences with the corresponding ORFs deduced from the nucleotide sequence(More)
Cultural differences in emotion perception have been reported mainly for facial expressions and to a lesser extent for vocal expressions. However, the way in which the perceiver combines auditory and visual cues may itself be subject to cultural variability. Our study investigated cultural differences between Japanese and Dutch participants in the(More)
Anxious individuals have been shown to interpret others’ emotional states negatively. Since most studies have used facial expressions as emotional cues, we examined whether trait anxiety affects the recognition of emotion in a dynamic face and voice that were presented in synchrony. The face and voice cues conveyed either matched (e.g., happy face and(More)
The plant growth retardant S-(+)-uniconazole (UNI-OH) is a strong inhibitor of abscisic acid (ABA) 8'-hydroxylase, a key enzyme in the catabolism of ABA, a plant hormone involved in stress tolerance, stomatal closure, flowering, seed dormancy, and other physiological events. In the present study, we focused on the two polar sites of UNI-OH and synthesized(More)
A chitinase gene (vChti-1) encoded by the Chlorella virus CVK2 was cloned and characterized. The vChti-1 open reading frame consisted of 2508 bp corresponding to 836 amino acid residues. The predicted amino acid sequence contained two sets of a family 18 catalytic domain that is responsible for chitinase activity. Northern blot analysis revealed that the(More)
Twenty-one patients with myeloperoxidase-antineutrophil cytoplasmic autoantibody (MPO-ANCA)-associated vasculitis were treated using cytapheresis. Of these, 17 were treated for glomerulonephritis and four were treated for pulmonary hemorrhage. The overall survival rate was 85.7% with a follow-up duration of 24.0 +/- 13.8 months. In the 17 patients with(More)
To develop a specific inhibitor of abscisic acid (ABA) 8'-hydroxylase, a key enzyme in the catabolism of ABA, a plant hormone involved in stress tolerance, seed dormancy, and other various physiological events, we designed and synthesized conformationally restricted analogues of uniconazole (UNI), a well-known plant growth retardant, which inhibits a(More)
