The primary structure of a glyceraldehyde-3-phosphate dehydrogenase gene from Saccharomyces cerevisiae.

The complete nucleotide sequence of the coding, as well as the flanking noncoding regions, of a yeast glyceraldehyde-3-phosphate dehydrogenase gene was determined. Both the 5' and 3' noncoding sequences are extremely AT-rich and regions of partial dyad symmetry are present immediately adjacent to the 5' and 3' ends of the translated portion of the gene. The sequence AAUAAA is present in the 3' noncoding region of this gene and is a part of an extensive region of dyad symmetry which is structurally related to the 3'-terminal portion of both procaryotic mRNAs, as well as some eukaryotic mRNAs. The coding region of this gene does not contain intervening sequences. Establishment of the primary structure of this glyceraldehyde-3-phosphate dehydrogenase gene provides a basis for further studies involving in vitro mutation of the gene and subsequent analysis of gene expression in vivo.
