已从小牛肝中纯化出副甲状腺素,并建立了其一级序列,除了在多肽链的中心部分含有约11个氨基酸残基的片段。牛甲状旁腺素含有约101个氨基酸残基,与大鼠甲状旁腺素具有90%的同一性,在第21、57和58位用Glu取代Asp,在第60和63位用Asp取代Glu,在第77位用Ala取代瓦尔。三个非保守性取代是Ala取代第81位的Thr,Leu取代第78位的Arg,和瓦尔取代第79位的Lys。一对碱性氨基酸残基的最后两个位置被疏水性氨基酸残基取代可能是牛和大鼠多肽色谱行为差异的原因。NH 2-末端的分析采用了一种新的去封闭程序,该程序也用于分析大鼠甲状旁腺素,需要校正先前公布的该多肽的NH 2-末端序列。
Parathymosin has been purified from calf liver and its primary sequence established, except for a segment containing approximately 11 amino acid residues in the central part of the polypeptide chain. Bovine parathymosin contains approximately 101 amino acid residues and shows 90% identity with rat parathymosin, with substitution of Glu for Asp at positions 21, 57, and 58, Asp for Glu at positions 60 and 63, and Ala for Val at position 77. Three nonconservative substitutions were Ala for Thr at position 81, Leu for Arg at position 78, and Val for Lys at position 79. The replacement at the last two positions of a pair of basic by hydrophobic amino acid residues may account for differences in chromatographic behavior observed for the bovine and rat polypeptides. Analysis of the NH2-terminus employed a new deblocking procedure which was also employed to analyze rat parathymosin, requiring correction of the previously published NH2-terminal sequence for that polypeptide.
