1. Expressão heteróloga, purificação e caracterização das proteínas humanas DCRA (Down Syndrome Critical Region Gene A) e DSCR8 (Down Syndrome Critical Region Gene 8).
Down syndrome is the most frequent cause of mental retardation affecting millions of people worldwide and results from full or partial trisomy of chromosome 21 (HC21). Rare cases of partial trisomy allowed the identification of a small region in HC21 common to all carriers called Down Syndrome Critical Region. The genes DCRA and DSCR8, mapped to this region,

2. Nucleotide sequence of dcrA, a Desulfovibrio vulgaris Hildenborough chemoreceptor gene, and its expression in Escherichia coli.
The amino acid sequence of DcrA (Mr = 73,000), deduced from the nucleotide sequence of the dcrA gene from the anaerobic, sulfate-reducing bacterium Desulfovibrio vulgaris Hildenborough, indicates a structure similar to the methyl-accepting chemotaxis proteins from Escherichia coli, including a periplasmic NH2-terminal domain (Mr = 20,700) separated from the

3. DcrA, a c-type heme-containing methyl-accepting protein from Desulfovibrio vulgaris Hildenborough, senses the oxygen concentration or redox potential of the environment.
The amino acid sequence of DcrA from Desulfovibrio vulgaris Hildenborough, a strictly anaerobic, sulfate-reducing bacterium, indicated homology with the methyl-accepting chemotaxis proteins from enteric bacteria (A. Dolla, R. Fu, M. J. Brumlik, and G. Voordouw, J. Bacteriol. 174:1726-1733, 1992). The homology is restricted to the cytoplasmic C-terminal signa

4. Identification of Chlamydia trachomatis Genomic Sequences Recognized by Chlamydial Divalent Cation-Dependent Regulator A (DcrA)
The Chlamydia trachomatis divalent cation-dependent regulator (DcrA), encoded by open reading frame CT296, is a distant relative of the ferric uptake regulator (Fur) family of iron-responsive regulators. Chlamydial DcrA specifically binds to a consensus Escherichia coli Fur box and is able to complement an E. coli Fur mutant. In this report, the E. coli Fur

5. Genetic control of the resistance to phage C1 of Escherichia coli K-12.
Escherichia coli K-12 lytic phage C1 was earlier isolated in our laboratory. Its adsorption is controlled by at least three bacterial genes: dcrA, dcrB, and btuB. Our results provide evidence that the dcrA gene located at 60 min on the E. coli genetic map is identical to the sdaC gene. This gene product is an inner membrane protein recently identified as a p

6. Identification of a large family of genes for putative chemoreceptor proteins in an ordered library of the Desulfovibrio vulgaris Hildenborough genome.
A library of 879 recombinant lambda phages, constructed for the genome of Desulfovibrio vulgaris Hildenborough, has been ordered by restriction fingerprinting. Restriction endonuclease HinfI digestion patterns were entered into a data base and sorted into 87 overlapping groups (contigs), with 19 clones remaining unattached. Eight of ten cloned genes of D. vu

7. Deletion of the rbo Gene Increases the Oxygen Sensitivity of the Sulfate-Reducing Bacterium Desulfovibrio vulgaris Hildenborough
The rbo gene of Desulfovibrio vulgaris Hildenborough encodes rubredoxin oxidoreductase (Rbo), a 14-kDa iron sulfur protein; forms an operon with the gene for rubredoxin; and is preceded by the gene for the oxygen-sensing protein DcrA. We have deleted the rbo gene from D. vulgaris with the sacB mutagenesis procedure developed previously (R. Fu and G. Voordouw
