脱氧马尿苷合酶催化脱氧马尿苷 [Nε-(4-氨基丁基) 赖氨酸] 的形成。这种修饰的赖氨酸残基是真核起始因子 5A (eIF5A) 1 中的高尿嘧啶 [Nε-(4-氨基-2-羟丁基) 赖氨酸] 翻译后合成的关键中间体(Park 等人综述,1993,1997)。 Hypusine 和 eIF5A 存在于所有检查的真核生物和某些古细菌中,但不存在于真细菌中(Gordon 等,1987;Schümann 和 Klink,1989;Bartig 等,1990;Park 等,1993,1997)。 Hypusine 对于真核细胞增殖的本质已被强烈提及(Byers 等,1992;Park 等,1993,1997;Byers 等,1994),并且最近在 eIF5A 基因失活的实验中得到证实(Schnier 等,1991;Schwelberger 等,
Deoxyhypusine synthase catalyses the formation of deoxyhypusine [Nε-(4-aminobutyl) lysine]. This modified lysine residue is the key intermediate in the posttranslational synthesis of hypusine [Nε-(4-amino-2-hydroxybutyl) lysine] in eukaryotic initiation factor 5A (eIF5A) 1 (reviewed in Park et al., 1993, 1997). Hypusine and eIF5A occur in all eukaryotes examined, and in certain archaea, but not in eubacteria (Gordon et al., 1987; Schümann and Klink, 1989; Bartig et al., 1990; Park et al., 1993, 1997). The essential nature of hypusine for eukaryotic cell proliferation has been strongly implicated (Byers et al., 1992; Park et al., 1993, 1997; Byers et al., 1994) and recently established in experiments in which inactivation of the genes for eIF5A (Schnier et al., 1991; Schwelberger et al.,
