A greenish yellow pigmented bacterial strain, designated GR5, was recently isolated from a freshwater culture pond for a soft-shell turtle. Phylogenetic analyses based on 16S rRNA gene sequences indicate that strain GR5 belongs to the genus Rheinheimera and its only closest neighbor is the type strain of Rheinheimera texasensis (98.2%). Based on the(More)
A brownish yellow pigmented bacterial strain, designated antisso-27, was recently isolated from a water area of saltpan in Southern Taiwan. Phylogenetic analyses based on 16S rRNA gene sequences indicate that strain antisso-27 belongs the genus Aquimarina in the family Flavobacteriacea and its only closest neighbor is Aquimarina spongiae (96.6%). Based on(More)
The small nanH gene encoding the neuraminidase from Clostridium perfringens ATCC 10543 was cloned in JM109 using pUC19 as a vector. Sequence analysis revealed an ORF encoding 382 amino acids without a signal peptide sequence. Four regions of amino-acid sequence, 71-82, 140-151, 208-219, and 255-266 constituted four repeated and conserved sequence(More)
Two distinct metabolic pathways of 5-fluorouracil are proposed in Escherichia coli. The first metabolic pathway is a reductive degradation with the formation of dihydrofluorouracil as the first metabolite. The second metabolic pathway is shown to be a hydroxylating degradation, possibly with the formation of 5-hydro-6-hydroxy-5-fluorouracil as the first(More)
