Abstract

We report the isolation and sequence of the Schizosaccharomyces pombe ade4 gene which encodes the glutamine phosphoribosylpyrophosphate amidotransferase, the first enzyme of the purine nucleotide de-novo biosynthetic pathway. The enzyme contains 533 amino acids and its sequence exhibits homologies to the corresponding enzymes of Saccharomyces cerevisiae, Escherichia coli, Bacillus subtilis, chicken, rat, and human. In contrast to the situation in S. cerevisiae, adenine does not repress ade4 expression at the mRNA level and also other nutritional signals seem not to affect its expression.
