  • Title: Molecular cloning and sequencing of a cDNA encoding N alpha-acetyltransferase from Saccharomyces cerevisiae.
    Author: Lee FJ, Lin LW, Smith JA.
    Journal: J Biol Chem; 1989 Jul 25; 264(21):12339-43. PubMed ID: 2663856.
    Abstract:
    Acetylation is the most frequently occurring chemical modification of the alpha-NH2 group of eukaryotic proteins and is catalyzed by an N alpha-acetyltransferase. Recently, a eukaryotic N alpha-acetyltransferase was purified to homogeneity from Saccharomyces cerevisiae, and its substrate specificity was partially characterized (Lee, F.-J. S., Lin L.-W., and Smith, J. A. (1988) J. Biol. Chem. 263, 14948-14955). This article describes the cloning from a yeast lambda gt11 cDNA library and sequencing of a full length cDNA encoding yeast N alpha-acetyltransferase. DNA blot hybridizations of genomic and chromosomal DNA reveal that the gene (so-called AAA1, amino-terminal, alpha-amino, acetyltransferase) is present as a single copy located on chromosome IV. The use of this cDNA will allow the molecular details of the role of N alpha-acetylation in the sorting and degradation of eukaryotic proteins to be determined.
