[Abstract] Digestion of chromatin by micrococcal nuclease MNase followed by high throughput sequencing allows us to determine the location and occupancy of nucleosomes on the genome. Here in this protocol we have described optimized conditions of MNase digestion of filamentous fungus Neurospora crassa chromatin ...

[Abstract] Density gradient centrifugation has been utilized to characterize the subcellular distribution of physiologically relevant enzymes in yeasts and filamentous fungi (Leal-Morales et al., 1988; Martínez et al., 1989; Kamada et al., 1991). This approach is now potentiated by protein tagging and live imaging ...
