Journal Article

The Drosophila glutathione S-transferase 1-1 is a dimer of a 209 amino acid subunit, designated DmGST1. DmGST1 is encoded by a member of a multigene family. Sequence analysis of a genomic clone for GST1 revealed that it is encoded by an intronless gene. We designate this gene and its other family members the GST D genes in the glutathione S-transferase gene superfamily. The Drosophila GST D genes are mapped by in situ hybridization to chromosome 3R at 87B of the polytene chromosome, which is flanked by the two clusters of hsp70 genes at 87A7 and 87C1. Cytogenetic data in the literature indicated that a puff occurred in this region under heat shock. We report that the glutathione S-transferase activity in Kco cells as determined by conjugation with 1-chloro-2,4-dinitrobenzene is elevated slightly to two-fold under heat shock. The implication of this finding is discussed.
