Characterization of the genes and proteins of a two-component system from the hyperthermophilic bacterium Thermotoga maritima.

abstract：:Cryptococcus neoformans is an important pathogenic fungus that has been classified as a basidiomycete. Little is known of the molecular genetics of this fungal pathogen. To begin such studies, we devised a procedure for extraction of DNA from cryptococci; this method involved the use of the cell wall-active enzyme Nov...
