Zusammenfassung: | NEW MATERIAL:A proteinic essential substance Ps-1 relating to manifestation of insulin secretion-enhancing activity having molecular weight: 28000+ or -1200, protein content: >=98wt.%, ratios of amino acid components (muM/100muM) of, Asp: 9.3+ or -1.0, Thr: 7.4+ or -0.8, Ser: 10.6+ or -1.0, Glu: 10.6+ or -1.0, Pro: 4.4+ or -0.5, Gly: 11.2+ or -1.0, Ala: 10.6+ or -1.0, Cys/2: 1.3+ or -0.3, Val: 6.7+ or -0.7, Met: 1.6+ or -0.3, Ile: 3.2+ or -0.4, Leu: 5.5+ or -0.6, Tyr: 4.6+ or -0.5, Phe: 3.5+ or -0.4, Lys: 2.2+ or -0.3, His: 1.7+ or -0.3 and Arg: 5.9+ or -0.6, and isoelectric point: pH5.8. USE:Curing agent of diabetes. PREPARATION:For instance, Bordetella pertussis is cultured in shaking in medium and cultured solution is centrifuged to collect supernatant solution, then the solution is treated in hydroxyapatite column, thus adsorbed substance is eluted and the eluate is subjected to gel filtration, then purified to afford the aimed proteinic essential substance Ps-1. |
