Deoxyhypusine synthase activity is essential for cell viability in the yeast Saccharomyces cerevisiae.

The Journal of biological chemistry - 16 Jan 1998

Park M H, Joe Y A, Kang K R

Abstract excerpt

Deoxyhypusine synthase catalyzes the first step in the posttranslational synthesis of an unusual amino acid, hypusine (N epsilon-(4-amino-2-hydroxybutyl)lysine), in the eukaryotic translation initiation factor 5A (eIF-5A) precursor protein. The null mutation in the single copy gene, yDHS, encoding deoxyhypusine synthase results in the loss of viability in the yeast Saccharomyces cerevisiae. Upon depletion of...
