Two endothelial cell growth factors (ECGF) have been purified from bovine brain and termed alpha- and beta-ECGF [Burgess, W. H., Mehlman, T., Friesel, R., Johnson, W. V. & Maciag, T. (1985) J. Biol. Chem. 260, 11389-11392]. Amino acid sequence analysis indicates that beta-ECGF represents a 20 amino acid amino-terminal extension of alpha-ECGF and a 14 amino acid amino-terminal extension of acidic fibroblast growth factor. These data indicate that both alpha-ECGF and acidic fibroblast growth factor may be derived from beta-ECGF by posttranslational processing. Analysis of the amino-terminal 14 residues of beta-ECGF by fast-atom-bombardment mass spectrometry established the amino acid sequence of this region and the identity of the blocking group at the amino terminus (acetyl).
已从牛脑中纯化出两种内皮细胞生长因子(ECGF),分别命名为α-ECGF和β-ECGF [伯吉斯,W. H.,梅尔曼,T.,弗里塞尔,R.,约翰逊,W. V. & 马西亚格,T.(1985年)《生物化学杂志》260,11389 - 11392]。氨基酸序列分析表明,β-ECGF代表α-ECGF的20个氨基酸的氨基末端延伸以及酸性成纤维细胞生长因子的14个氨基酸的氨基末端延伸。这些数据表明,α-ECGF和酸性成纤维细胞生长因子可能都是通过翻译后加工从β-ECGF衍生而来。通过快原子轰击质谱法对β-ECGF的氨基末端14个残基进行分析,确定了该区域的氨基酸序列以及氨基末端封闭基团(乙酰基)的身份。
