    • Disclosed are (1) a mutein of a fibroblast growth factor (FGF), the DNA having introduced therein at least one nucleotide sequence coding for a glycosylation site, (2) a DNA coding for the mutein of (1), (3) a vector containing the DNA of (2), (4) a transformant transformed with the vector of (3), and (5) a process for producing the mutein which comprises cultivating in a culture medium the transformant of a yeast or animal cell transformed with a vector of (3), and producing and accumulating the mutein of (1) in the culture medium, whereby the FGF mutein into which at least one glycosylation site has been introduced is improved in productivity, stability and activities, and advantageously used as medicine.
    • 公开了(1)成纤维细胞生长因子(FGF)的突变蛋白,其中引入了至少一个编码糖基化位点的核苷酸序列的DNA,(2)编码(1),(3)的突变蛋白的DNA 含有(2)的DNA的载体,(4)用(3)的载体转化的转化体,和(5)一种产生突变蛋白的方法,其包括在培养基中培养转化了酵母或动物细胞的转化体 (3)的载体,并且在培养基中产生和积累(1)的突变蛋白,从而提高了其中引入至少一个糖基化位点的FGF突变蛋白的生产力,稳定性和活性,并且有利地用作药物 。
