The role of the conserved sequence region III in the promoter regions of the amylase-encoding genes amyB, glaA and agdA of Aspergillus oryzae was examined. Introduction of multiple copies of the region III fragment into the agdA promoter resulted in a significant increase in promoter activity at the transcriptional level. This result suggests that the(More)
The peptidyl prolyl cis/trans isomerase Pin1 specifically binds phosphorylated Ser/Thr-Pro protein motifs and catalyzes the cis/trans isomerization of the peptide bond. Accumulating studies have revealed that Pin1 isomerase activity is regulated by its post-translational modifications, including phosphorylation and oxidation. Various transcription factors(More)
lacA coding for beta-galactosidase (beta-gal) was cloned from the genomic DNA of Aspergillus oryzae RIB40. There were 9 exons in lacA and the coding region of 3,015 bp encoded a protein of 1,005 aa with a deduced molecular mass of 109,898. A. oryzae lacA was highly homologous to fungal beta-gals, with the highest aa identity of 70.7% to A. niger lacA, and(More)
