Protein targeting to the nucleus has been studied extensively in animal and yeast systems; however, nothing is known about nuclear targeting in plants. The Opaque-2 (02) gene produces a regulatory protein that is responsible for inducing transcription of the a-zein class of storage proteins in maize kernels. The cloned 02 gene encodes a protein that contains a leucine zipper DNA binding domain ...

Monoamine oxidase (MAO) [EC 1.4.3.4 monoamine: oxygen oxidoreductase (deami nating)] has been shown to be firmly bound to the mitochondrial membrane (1-4), and its solubilization causes changes in its properties (5-7). This paper describes the solubilization of MAO from mitochondria of hog kidney cortex by a mixture of Triton-X 100 and sodium cholate and changes in the substrate specificities o...

Most mushrooms are thermo-sensitive to temperatures over 23°C, which greatly restricts their agricultural cultivation. Understanding mushroom's innate heat-tolerance mechanisms may facilitate genetic improvements of their thermotolerance. Agaricus bisporus strain 02 is a relatively thermotolerant mushroom strain, while strain 8213 is quite thermo-sensitive. Here, we compared their responses at ...
