This study addresses the importance of a heat-shock-responsive cis-acting DNA element and its transcriptional regulator, which play key roles in the regulation of the Spirulina-desD gene on exposure to high temperatures. Temperature response analysis studies showed that the AT-rich region that is located between nt -98 to -80 of the Spirulina-desD gene promoter serves as a binding site for its transcriptional regulator. LC-MS/MS analysis of the DNA-binding protein complex revealed that the amino acid sequences of the bound proteins were homologous to those of several proteins, including a DNA-binding protein, heat shock protein-90 (Hsp90 or HtpG), GroEL and various protein kinases. In addition, western blot analysis indicated that the chaperones GroEL and Hsp90 and a dephosphorylation reaction played a role in the response to elevated temperatures. We conclude that the regulatory DNA segments and the corresponding regulatory binding proteins are distinct for each particular stress condition. This is true, irrespective of whether the regulatory mechanisms that govern the expression of the cold- and heat-regulated desD gene depend on similar phosphorylation- and dephosphorylation-dependent conformational changes that modulate the association of the co-chaperone.
