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.

Iimura Y, Tatsumi K.


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.
