We hypothesized that the thermal stability of Moloney murine leukaemia virus reverse transcriptase (MMLV RT) will increase with increases in its ability to bind with a template-primer (T/P). To test this hypothesis, we introduced positive charges into MMLV RT by site-directed mutagenesis at positions that have been implicated in the interaction with T/P. Thirty-six variants were constructed in ...
Recently we have shown that Mos could activate myogenic differentiation by promoting heterodimerisation of MyoD and E12 proteins. Here, we demonstrate that MyoD can be efficiently phosphorylated by in vitro kinase assay with purified Mos immunoprecipitated from transfected cells. Comparative two-dimensional tryptic phosphopeptide mapping combined with site-directed mutagenesis revealed that Mos...
The conventional method for cloning a DNA fragment is to insert it into a vector and ligate it. Although this method is commonly used, it is labor intensive because the ratio and concentrations of the DNA insert and the vector need optimizing. Even then, the resultant library is often plagued with unwanted plasmids that have no inserts or multiple inserts. These species have to be eradicated to...
Photoactivatable fluorescent proteins bring new dimension to the analysis of protein dynamics in the cell. Protein tagged with a photoactivatable label can be visualized and tracked in a spatially and temporally defined manner. Here, we describe a basic rational design strategy to develop monomeric photoactivatable proteins using site-specific mutagenesis of common monomeric red-shifted fluores...
