The amino acid sequence of the COOH-terminal light chain portion of bovine high-molecular-weight kininogen (HMWK) was reinvestigated, since some discrepancy of the amino acid sequence, which we reported previously, was found in the cDNA analysis for bovine HMWK (Kitamura, N. et al. (1983) Nature 305, 545-548). The results showed that the following positions in the light chain should be revised: Gln-23 to Glu, the sequence Asp-Asp-Asp-Trp-Ser at positions 62-66 to Ser-Asp-Asp-Asp-Trp, Asp-102 to Asn, and Gln-109 to Glu.
由于在对牛高分子量激肽原(HMWK)的cDNA分析中发现了我们之前报道的氨基酸序列存在一些差异(北村,N.等人(1983年)《自然》305,545 - 548),因此对牛HMWK羧基末端轻链部分的氨基酸序列进行了重新研究。结果表明,轻链中的以下位置应进行修正:第23位的谷氨酰胺(Gln)变为谷氨酸(Glu),第62 - 66位的天冬氨酸 - 天冬氨酸 - 天冬氨酸 - 色氨酸 - 丝氨酸(Asp - Asp - Asp - Trp - Ser)序列变为丝氨酸 - 天冬氨酸 - 天冬氨酸 - 天冬氨酸 - 色氨酸(Ser - Asp - Asp - Asp - Trp),第102位的天冬氨酸(Asp)变为天冬酰胺(Asn),以及第109位的谷氨酰胺(Gln)变为谷氨酸(Glu)。
