The Rhizopus oryzae secreted aspartic proteinase gene family: an analysis of gene expression

Article Abstract:

Experiments were performed to investigate the regulation of individual members of the secreted aspartic proteinase (sap) gene family in Rhizopus oryzae. Results showed that an acidic medium and either a nitrogen or sulphur derepression were needed for the transcription of the three members of the gene family. It was also observed that while increased transcript levels were seen in the presence of exogenous protein, sap4 was not expressed in the condition. Moreover, it was proposed that SAP1-SAP4 have almost identical substrate-binding sites and substrate specificity.

Meeting report: the filaments that bind us

Article Abstract:

European Molecular Biology Organization's 'Genome structure, function and expression' workshop held Sep. 2-7, 1995, in Ambleside, UK, focused on the molecular biology of filamentous fungi. John Taylor described a class of eukaryotes whose evolution can be patterned after that of both animals and plants. The workshop also highlighted the progress in genetic and molecular analysis of the non-filamentous fungi Saccharomyces cerevisiae and Schizosaccharomyces pombe.
