Braga, J. C., Company, M., García-Hernández, M., Linares, A., Rivas, P., Sandoval, J.
[ES] Se estudia la bioestratigrafía y la paleontología de cuatro secuencias de Albense superior-Vraconense de la región de Huéscar (Cordilleras Béticas, España). Las faunas de ammonites...
Comparative study of various hydrogen ion buffers to assay Zn(2+)-dependent beta-lactamases.
Benitez, M J, Company, M, Arevalillo, A, Jiménez, J S
The low Zn2+ complex formation constants, the capacity to degrade penicillin G in combination with Zn2+, and UV absorbance make 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid,...
Identification of a Ty1 regulatory sequence responsive to STE7 and STE12.
Company, M, Adler, C, Errede, B
Ty1 activation of gene expression observed in haploid cell types of Saccharomyces cerevisiae requires the STE7 and STE12 gene products. An activator sequence within Ty1 that is responsive to these...
Ty1 sequence with enhancer and mating-type-dependent regulatory activities.
Errede, B, Company, M, Hutchison, C A
Some insertion mutations in Saccharomyces cerevisiae activate the expression of adjacent structural genes. The CYC7-H2 mutation is a Ty1 insertion 5' to the iso-2-cytochrome c coding region of CYC7....
Ty transposable-element insertion mutations of Saccharomyces cerevisiae can cause cell-type-dependent activation of adjacent-gene expression. Several cis-acting regulatory regions within Ty1 are...
Transcriptional analysis of Ty1 deletion and inversion derivatives at CYC7.
One class of Ty insertion mutation in Saccharomyces cerevisiae activates expression of adjacent structural genes. The CYC7-H2 mutation, in which a Ty1 element is inserted 5' to the iso-2-cytochrome c...
An anomalous Ty1 structure attributed to an error in reverse transcription.
Errede, B, Company, M, Swanstrom, R
We have determined the nucleotide sequence of both delta elements of a Ty1 transposon inserted near the CYC7 gene in the Saccharomyces cerevisiae CYC7-H2 mutant. The upstream delta element in this...
Ty transposable element insertion mutations of Saccharomyces cerevisiae can cause cell-type-dependent activation of adjacent gene expression. Several cis-acting regulatory regions within Ty1 that are...
Errede, B, Company, M, Ferchak, J D, Hutchison, C A, Yarnell, W S
The DNA sequence of the Ty1 activating region from the CYC7-H2 mutant of Saccharomyces cerevisiae is presented. Analysis of the data revealed the presence of four simian virus 40-type enhancer core...
