Isoforms of eIF-5A: senescence-induced eIF5A; wounding-induced eIF-5A; growth eIF-5A; and DHS
The present invention relates to unique isoforms of eukaryotic initiation Factor 5A (“eIF-5A”): senescence-induced eIF-5A; wounding-induced eIF-5A; and growth eIF-5A, as well as polynucleotides that encode these three factors. The present invention also relates to methods involving modulating the expression of these factors. The present invention also relates to deoxyhypusine synthase (“DHS”), polynucleotides that encode DHS, and methods involving modulating the expression of DHS.
1. An isolated deoxyhypusine synthase (DHS) polypeptide with at least 95% sequence identity to SEQ ID NO: 73.
2. The isolated polypeptide of claim 1 , wherein the polypeptide comprises or consists of SEQ ID NO: 73.
3. The isolated polypeptide of claim 1 , wherein the DHS is from alfalfa.
