The genus Caulobacter is found in a variety of habitats and is known for its ability to thrive in low-nutrient conditions. K31 is a novel Caulobacter isolate that has the ability to tolerate copper and chlorophenols, and can grow at 4 ° C with a doubling time of 40 h. K31 contains a 5.5 Mb chromosome that codes for more than 5500 proteins and two large plasmids (234 and 178 kb) that code for 43...

Four bacteriophages (A16, CK235, phi 1.2 and K31) which specifically attack different encapsulated strains of Escherichia coli have been shown to be related to bacteriophage T7 (which is unable to grow on encapsulated hosts). The conclusion that phages A16 and CK235 are related to T7 is based on similarities in the pattern of expression of intracellular phage proteins, early appearance, in infe...

This paper presents an advanced characterization method to obtain anisotropic intensive piezoelectric loss for k31, k33 and k15 mode. By redefining half-power bandwidth, new procedure is suggested with effective k31-k15 geometry using crystallographic approach. Without low capacitance bar structure, the relative error not worth consideration. Difficulty of shear mode analysis due spurious peaks...

PafA, the prokaryotic ubiquitin-like protein (Pup) ligase, catalyzes the Pup modification of bacterial proteins and targets the substrates for proteasomal degradation. It has been reported that that M. smegmatis PafA can be poly-pupylated. In this study, the mechanism of PafA self-pupylation is explored. We found that K320 is the major target residue for the pupylation of PafA. During the self-...

The non-homologous end joining (NHEJ) pathway is used in diverse species to repair chromosome breaks, and is defined in part by a requirement for Ku. We previously demonstrated mammalian Ku has intrinsic 5' deoxyribosephosphate (5'dRP) and apurinic/apyrimidinic (AP) lyase activity, and showed this activity is important for excising abasic site damage from ends. Here we employ systematic mutagen...

To develop an effective technology for conversion of inorganic arsenic to methylated organic compounds by using microorganisms, we have searched microorganisms the methylation ability that are adequately applicable detoxification process. As a result, isolated arsenic-methylating bacteria Cellulomonas sp. K31.

We develop a model linking maximum damage awards available to plaintiffs in wrongful termination lawsuits, workers’ propensity to sue as a function of experience, and returns to experience. Using Equal Employment Opportunity Commission data on protected-worker discrimination complaints and labor-market data from the Current Population Survey, we examine how returns to experience among protected...

Arguably the most aggressive affirmative action program ever implemented in the United States was a series of court-ordered racial hiring quotas imposed on municipal police departments. My best estimate of the effect of court-ordered affirmative action on work-force composition is a 14-percentage-point gain in the fraction African American among newly hired officers. Evidence on police performa...

Formula 1 terdiri semen : pasir fly dengan K11 (1 5 0;); K12 0,5); K13 1). 2 putih K21 K22 K23 3 ...

The Foxp3 transcription factor is the master regulator of regulatory T cell (Treg) differentiation and function. Its activity is regulated by reversible acetylation. Using mass spectrometry of immunoprecipitated proteins, we identify three novel acetylation sites in murine Foxp3 (K31, K262, and K267) and the corresponding sites in human FOXP3 proteins. Newly raised modification-specific Abs aga...
