A cDNA encoding for a heat shock protein 30 (HSP30) of Aspergillus nidulans and the promoter region of its gene were analyzed for their primary structures. The promoter region had no heat shock element but possessed three inverted repeat sequences. Northern blot hybridization indicated that the expression of the HSP30 gene was high at a normal temperature and was slightly accelerated at elevated temperatures in A. nidulans cells. Although the deduced amino acid sequence of the A. nidulans HSP30 had a domain highly conserved among other small HSPs from different species, it showed a sequence homology of only 42% even in comparison with the most closely related molecular species, Neurospora crassa HSP30. These findings suggest that the present HSP30 belongs to a novel subfamily of low-molecular-weight HSPs.
