Structure of Genes for Hsp30 from the White-rot fungus Coriolus versicolor and the Increase of their Expression by Heat Shock and Exposure to a Hazardous Chemical

Abstract

  We isolated and analysed two genomic DNAs that encode the heat-shock protein Hsp30 from Coriolus versicolor. The amino acid sequences substitute only three amino acid substitutions. The promoter regions contain the consensus heat-shock element, a xenobiotic-response element, a stress-response element, and a metal-response element. The levels of mRNAs for Hsp30 increased markedly after exposure of C. versicolor to pentachlorophenol and levels were higher than those after heat shock.
