Conditional lethal YidC mutants have been isolated to decipher the role of YidC in the assembly of Sec-dependent and Sec-independent membrane proteins. We now show that the membrane insertion of the Sec-independent M13 procoat-lep protein is inhibited in a short time in a temperature-sensitive mutant when shifted to the nonpermissive temperature. This provides an additional line of evidence tha...

An analysis of the CN and CH band strengths measured in a large sample of M71 and M13 main sequence stars by Cohen (1999a,b) is undertaken using synthetic spectra to quantify the underlying C and N abundances. In the case of M71 it is found that the observed CN and CH band strengths are best matched by the identical C/N/O abundances which fit the bright giants, implying: 1) little if any mixing...

The construction of recombinant M13 phages containing adenovirus DNA inserts was undertaken to provide strand-specific hybridization probes for analyses of adenovirus type 2 RNA transcripts. A library of molecular probes was constructed by cloning restriction endonuclease fragments of adenovirus types 2 and 5 DNA in the duplex replicative form DNA of the single-stranded bacteriophage vectors, M...

Geobacillus stearothermophilus is the main thermophilic spore former involved in flat sour spoilage of canned foods. Three typing methods were tested and applied to differentiate strains at intra-species level: panC sequence analysis, REP-PCR and M13-PCR. panC gene was highly conserved within the studied strains, suggesting a low intra-specific diversity. This was supported by REP-PCR primary a...

Analyses of genetic diversity within populations could be of great benefit to plant genetic resources conservation . In order to identify genetic markers that are variable within populations, the genome of Phaseolus vulgaris was screened with several DNA sequences in order to identify hypervariable sequences . Polymorphisms were observed between Middle American and Andean cultivars using the pr...

BACKGROUND Cytochrome P450 monooxygenase constitutes a significant group of oxidative enzymes that can introduce an oxygen atom in a high regio- and stereo-selectivity mode. We used the Bacillus megaterium cytochrome P450 BM3 (CYP450 BM3) and its variants namely mutant 13 (M13) and mutant 15 (M15) for the hydroxylation of diverse class of flavonoids. RESULTS Among 20 flavonoids, maximum seven...

We have carried out a detailed abundance analysis for 21 elements in a sample of 25 stars with a wide range in luminosity from luminous giants to stars near the main sequence turnoff in the globular cluster M13 ([Fe/H] −1.50 dex) and in a sample of 13 stars distributed from the tip to the base of the RGB in the globular cluster M3 ([Fe/H] −1.39 dex). The analyzed spectra, obtained with HIRES at...

Availability of a rapid, accurate, and reliable point-of-care (POC) device for detection of infectious agents and pandemic pathogens, such as swine-origin influenza A (H1N1) virus, is crucial for effective patient management and outbreak prevention. Due to its ease of use, rapid processing, and minimal power and laboratory equipment requirements, the lateral-flow (immuno)assay (LFA) has gained ...
