Cell extracts were prepared from Trichosporon cutaneum grown with phenol or p-cresol, and activities were assayed for enzymes catalyzing conversion of these two carbon sources into 3-ketoadipate (beta-ketoadipate) and 3-keto-4-methyladipate, respectively. When activities of each enzyme were expressed as a ratio, the rate for methyl-substituted substrate being divided by that for the unsubstitut...

The most common form of hypersensitivity pneumonitis in Japan is summer-type hypersensitivity pneumonitis (SHP), which is caused by the inhalation of Trichosporon asahii or Trichosporon mucoides. To seek protein antigens relevant to the immunopathogenesis of SHP, we constructed a cDNA expression library of T. asahii, a major causative yeast species of SHP. Using the immunoscreening method, we i...
