ClpB disaggregase, in particular, ClpB3 from A. thaliana. ClpB3 was produced recombinantly in Escherichia coli and affinity-purified to near homogeneity. ClpB3 forms a hexameric complex in the presence of MgATP and displays intrinsic ATPase activity. We demonstrate that ClpB3 has ATPase activity in a wide range of pH and temperature values and is particularly resistant to heat. ClpB3 specifically targets unstructured polypeptides and mediates the reactivation of heat-denatured model substrates without the aid of the Hsp70 system. Overall,

Our quantum chemical computations have guided nuclear magnetic resonance experiments that confirm the increase in the gauche population as X goes from F to OH.The cuticular wax layer on leaf surfaces limits non-stomatal water loss to the atmosphere and protects against pathogen invasion. Although many genes associated with wax biosynthesis and wax transport in plants have been identified, their regulatory mechanisms remain largely unknown. Here, we show that the MYB transcription factor OsMYB60 positively regulates cuticular wax biosynt
