The proteins of a small subunit of A. salina ribosomes were separated into twenty seven basic proteins by two-dimentional gel electrophoresis and eluted from the gels by diffusion into 70% formic acid. The eluted proteins were then purified by using size-exclusion high-performance liquid chromatography(HPLC). Amino acid analyses were performed by the preparation of dimethylaminoazobenzenesulfonyl(DABS)derivatives of amino acids, followed by reverse-phase HPLC. It was found that the amino acid compositions of horse heart cytochrome C and two A. salina 40S ribosomal proteins(S6 and S8)determined by the present methods were similar to those determined by the conventional amino acid analyzer. This method allowed to determine amino acids in pmole range. The amino acid compositions of A. salina and rat liver 40S ribosomal proteins were compaired and the similality of amino acid compositions of the corresponding proteins of rat liver and A. salina are evaluated by the method of Cornish-Bowden [Cornish-Bowden(1980)Anal. Biochem., 105, 233~238]. Ten pairs of proteins(S2, S3, S4, S6, S7, S8, S15a, S16, S17 and S18)are positive in the“strong”test, six pairs of proteins(S14, S15, S20, S23, S24 and S26)are positive in the“weak”test and seven pairs of proteins(S9, S10, S11, S13, S27, S27a and S28)are not related.}, pages = {652--668}, title = {逆相 : 高速液体クロマトグラフィーを用いた微量アミノ酸分析によるArtemia salinaリボソーム小亜粒子蛋白質のアミノ酸組成 : ラットとの比較}, volume = {100}, year = {1986} }
