Here, by combining antibody mapping, N-terminal sequencing, and site-specific mutagenesis, we defined the amino-acid sequence of most of the LEKTI polypeptides physiologically generated in human epidermis.
Since the experimenter can control the mutagenesis directly by reducing the concentration or time of mutagenesis, we suggest that future phenotype sequencing experiments should use a substantially lower mutagenesis density than we employed, to boost the signal-to-noise ratio.
In this report, using extensive mutagenesis we identify a novel DNA sequence that functions as a core promoter element at the second start site of the hepatitis B virus (HBV) X mRNA which we have named XCPE2 (X core promoter element 2).
Therefore, through scanning mutagenesis we identified a 29-bp sequence within the SmaI- HaeIII fragment that contains bases important for origin bias.
As a baseline reference, an axenic wt clone, without any thermal tolerance selection or mutagenesis, was sequenced with the Roche 454 Junior Sequencer.
D620N and P316S mutations were introduced by PCR-mediated site-directed mutandnesequencedequenced to confirm their integrity.
We next performed bisulfite mutagenesis and sequencing of the Peg3 gDMR to more thoroughly examine individual gDMR cytosine methylation status.
In summary, according to the mutagenesis analysis and sequence comparisons, we suggest that electrostatic effects are responsible for the differential binding affinities between AZ and ODC and between AZ and AZI.
Vinculin exon 20-deletion (ΔEx20) constructs were generated using the QuikChange® site-directed mutagenesis kit (Stratagene), sequenced and subcloned.
Mutants were generated using DpnI mutagenesis, sequenced, and cloned into pUAST-AttB (Bischof et al., 2007 ).
