Phytochromes are widespread photoreceptors responsive to red and far-red light that exist in two photochromic forms Pr (inactive) and Pfr (active). The Pr --> Pfr conversion proceeds through a series of events initiated by Z-->E photoisomerization of the tetrapyrrole chromophore, believed to occur at C15 of the methine bridge between rings C and D. Recent crystal structures show that ring D in ...

The polymerase chain reaction was used to develop a method for the detection of Helicobacter pylori, a causative agent of gastritis, as well as for the elucidation of its mode of transmission. A genomic library of Helicobacter pylori DNA in Escherichia coli JM109 was constructed by cloning Hind III-digested DNA fragments into plasmid vector pUC18. The nucleotide sequences from seven recombinant...

A Gram-reaction-negative, rod-shaped, yellow-pigmented, motile by gliding bacterial strain, designated RU-4-M-4(T), was isolated from intertidal sediment of Sakhalin Island in Russia. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain RU-4-M-4(T) was related to the genus Algibacter and had highest 16S rRNA gene sequence similarity with Algibacter pectinivorans KACC 14153(...

The role of C17:0 and C15:0 in human health has recently been reinforced following a number of important biological and nutritional observations. Historically, odd chain saturated fatty acids (OCS-FAs) were used as internal standards in GC-MS methods of total fatty acids and LC-MS methods of intact lipids, as it was thought their concentrations were insignificant in humans. However, it has been...

The effect of composition on the ternary (NbCr2–TiCr2) C15 phase properties has been investigated, focusing upon the defect structure, elastic properties, and mechanical behavior. The C15 phase field is continuous between NbCr2–TiCr2, with a maximum phase field width of at least 7 at.% solubility. The defect mechanism is governed by anti-site constitutional defects for all alloys. Mechanically,...

Considerable amounts of odd-numbered fatty acids, such as non-hydroxy C15 and C17 and 3-hydroxy C11 and C13 acids, were found in lipopolysaccharides from Vibrio cholerae 35A3 (Inaba).

A Gram-reaction-negative, yellow-pigmented strain, designated EX36(T), was characterized using a polyphasic approach comprising phylogenetic, morphological and genotypic analyses. The endophytic strain was isolated from Zn/Cd-accumulating Salix caprea in Arnoldstein, Austria. Analysis of the 16S rRNA gene demonstrated that the novel strain is most closely related to members of the genus Spiroso...
