Klebsiella aerogenes urease gene cluster: sequence of ureD and demonstration that four accessory genes (ureD, ureE, ureF, and ureG) are involved in nickel metallocenter biosynthesis.
The region located immediately upstream from the Klebsiella aerogenes urease structural genes was sequenced and shown to possess an open reading frame capable of encoding a 29.8-kDa peptide.Expand

Characterisation of a chromosomally encoded catechol 1,2-dioxygenase (E.C. 1.13.11.1) from Alcaligenes eutrophus CH34
Alcaligenes eutrophus CH34 used benzoate as a sole source of carbon and energy, degrading it through the 3-oxoadipate pathway. All the enzymes required for this degradation were shown to be encodedExpand

Tumor necrosis factor alpha, interleukin 1 alpha, and interleukin 6 mRNA expressed by human astrocytoma cells after infection by three different strains ofToxoplasma gondii
The role of cytokines in the pathogenesis of toxoplasmosis remains unknown to a large extent, especially in the case of reactivation that occurs in immunocompromised patients. To assess theExpand

Sequence of the plastid rDNA spacer region of the brown alga Pylaiella littoralis (L.) Kjellm. Evolutionary significance
The DNA segment situated between the 16S and 23S rRNA genes belonging to the plastid genome of the brown alga Pylaiella littoralis (L.) Kjellm. has been sequenced. This small region (322 bp) containsExpand

Physical maps of the two circular plastid DNA molecules of the brown algaPylaiella littoralis (L.) Kjellm
SummaryTwo circular molecules of different sizes, both belonging to the chloroplast DNA of the brown algaPylaiella littoralis, have been observed by electron microscopy (Dalmon et al. 1983). CloneExpand

Presence of a 16S rRNA pseudogene in the bi-molecular plastid genome of the primitive brown alga Pylaiella littoralis. Evolutionary implications
SummaryThe plastid genome of the brown alga Pylaiella littoralis (L.) Kjellm. is composed of two different circular DNA molecules: the largest carries two rrn operons, and the smallest, only one copyExpand

Plastid genomes of the Rhodophyta and Chromophyta constitute a distinct lineage which differs from that of the Chlorophyta and have a composite phylogenetic origin, perhaps like that of the
SummaryA phylogenetic tree has been constructed from comparisons of entire 16S rRNA gene sequences from different prokaryotes and from several algal plastids. According to this study, and to previousExpand

Ribosomal RNA Genes and Pseudogenes of the Bi-Molecular Plastid Genome of the Brown Alga Pylaiella littoralis
The algae have long been classified into three main groups based on their plastidial pigments (Christensen, 1964). In this scheme all three groups have the same primary pigment, chlorophyll a, andExpand
