title: Functional cloning of a Dictyostelium discoideum cDNA encoding GMP synthetase.
abstract: A functional cloning procedure has been used to recover a cDNA coding for the GMP synthetase of Dictyostelium discoideum. The enzyme is encoded by a single gene, which is actively transcribed during growth, but not during development. The open reading frame encodes a protein of 718 amino acids with a predicted molecular mass of 79.6 kDa. The Dictyostelium enzyme has extensive homology with the GMP synthetase of Escherichia coli and regional homology to other glutamine amidotransferases.
