Specialized transducing phages for ribosomal protein genes of Escherichia coli
(National Academy of Sciences, 1975-01-01)Specialized lambda transducing phages have been isolated carrying approximately half the ribosomal protein genes of E. coli. These phages carry regions of the bacterial chromosome between aroE and fus. The ribosomal protein ... -
Cluster of genes in Escherichia coli for ribosomal proteins, ribosomal RNA, and RNA polymerase subunits
(National Academy of Sciences, 1975-07-01)This work was supported in part by the College of Agriculture and Life Sciences, University of Wisconsin, and by grants from the National Science Foundation (GB31086) and the National Institute of General Medical Sciences ... -
Involuntary Community: Conscientious Objectors at Patapsco State Park During World War II
(Maryland Center for History and Culture, 1977)IN MAY 1941 TWENTY-SIX IDEALISTS RETREATED INTO THE WOODS OF PATAPSCO State Park near Baltimore to form a community of pacifists in a nation on the verge of war. While the camp they established resembled many experiments ... -
Mapping of ribosomal protein genes by in vitro protein synthesis using DNA fragments of lambda fus3 transducing phage DNA as templates
(1977-10-25)hfus3 (or hfus2) transducing phage stimulates the synthesis of 27 ribosomal proteins, elongation factors EF-Tu and EF-G, and RNA polymerase subunit (Y in ultraviolet-irradiated Escherichia roli cells (see a preceding ... -
Characterization of hybrid plasmids carrying individual ribosomal ribonucleic acid transcription units of Escherichia coli
(American Society for Microbiology, 1977-12)We have screened the strains with ColE1 hybrid plasmids constructed by Clarke and Carbon (Cell 9:91-99, 1976) for the presence of ribosomal ribonucleic acid (rRNA) genes on the plasmids and identified 16 strains whose ... -
A Multiple-Task Performance Battery Presented on a CRT
(Defense Technical Information Center, 1978-04-15)A minicomputer controlled battery of tasks is provided which can be presented individually or in combination on a single peripheral device, a cathode ray tube CRT, and which uses the accompanying keyboard as the operators ... -
Operon-specific regulation of ribosomal protein synthesis in Escherichia coli
(National Academy of Sciences, 1979-12)We have cloned a DNA fragment harboring the genes for ribosomal proteins L2, L4, and L23 on a plasmid vector that contains a lac operator and promoter. The cloned ribosomal protein genes are now under the control of lacOP. ... -
High-efficiency, temperature-sensitive suppression of amber mutations in Escherichia coli
(American Society for Microbiology (ASM), 1981-01)We have constructed a high-copy-number plasmid carrying an allele of the supD gene (supD43,74). The plasmid conferred temperature-sensitive suppression of amber mutations. Strains carrying the plasmid exhibited 50 to 60% ... -
Oversynthesis of elongation factors G and Tu in Escherichia coli
(American Society for Microbiology (ASM), 1982-02)We induced the oversynthesis of elongation factors Tu and G by using multicopy plasmids carrying the structural genes for these proteins under the control of the lac operator-promoter. We found no evidence that accumulation ... -
The nucleotide sequence of the Escherichia coli fus gene, coding for elongation factor G.
(Oxford University Press, 1984-02-24)We have determined the nucleotide sequence of the Escherichia coli fus gene, which codes for elongation factor G. The protein product of the sequenced gene contains 703 amino acids, with a predicted molecular weight of ... -
Role of attenuation in growth rate-dependent regulation of the S10 r-protein operon of E. coli
(The European Molecular Biology Organization, 1984-07)We have investigated the transcription of the 11 gene S10 ribosomal protein operon of Escherichia coli under various growth conditions. The differential synthesis rate of structural gene message increases 2- to 2.5-fold ... -
The Making of a Baltimore Rowhouse Community: The Edmondson Avenue Area, 1915-1945

Classroom, Research, and Public History: An Integrated Approach
(University of California Press, 1985)AT A TIME when popular interest in history appears to be high, the historical enterprise seems unnecessarily fragmented. Classroom teachers, public agency officials, and research scholars-with their specialized functions ... -
Nucleotide sequence of the alpha ribosomal protein operon of Escherichia coli
(Oxford University Press, 1985-06-11)In Escherichia coli some 19 transcription units encoding the 52 ribosomal proteins are scattered throughout the genome. One of the units, the alpha operon, encodes genes for the ribosomal proteins S13, S11, S4 and L17 as ... -
Transcriptional control of the S10 ribosomal protein operon of Escherichia coli after a shift to higher temperature
(American Society for Microbiology, 1985-07)In the 5 to 10 min immediately following a shift from 30 to 42 degrees C, the differential synthesis rates of ribosomal proteins encoded by the 11-gene S10 operon are transiently decreased. This effect results largely from ... -
Precursor for elongation factor Tu from Escherichia coli
(American Society for Microbiology, 1986-02)The tufA gene, one of two genes in Escherichia coli encoding elongation factor Tu (EF-Tu), was cloned into a ColE1-derived plasmid downstream of the lac promoter-operator. In cells carrying this plasmid, the synthesis of ... -
Transcription of ribosomal genes during a nutritional shift-up of Escherichia coli
(American Society for Microbiology, 1986-09)We measured the differential transcription rates of individual ribosomal operons after a nutritional shift-up. All operons showed a transient increase in transcription. However, the response of the S10 ribosomal protein ... -
Spectral sensitivity of the compound eyes in the purple land crab, Gecarcinus lateralis
(1987-08-17)The spectral sensitivities(S(λ)) of dark-adapted compound eyes of the purple land crab Gecarcinus lateralis posses a broad maximum in the blue-green, 420-530 nm,when measured by electroretinographic (ERG) techniques. ... -
Autogenous control of the S10 ribosomal protein operon of Escherichia coli: genetic dissection of transcriptional and posttranscriptional regulation
(National Academy of Sciences, 1987-09)The S10 ribosomal protein operon is regulated autogenously by the product of one of the genes of the operon, the gene encoding ribosomal protein L4. We have used site-directed mutagenesis to isolate leader mutations affecting ... -
