The N-terminal sequences of two calf-thymus non-histone chromosomal proteins, HMG-1 and HMG-2, are compared. Both N-terminal sequences are basic, and differ at only one position. This contrasts with the C-terminal portion of HMG-1 which we have previously shown to be high in acidic residues. There is no obvious sequence homology with any of the known sequences of the histones.
对两种小牛胸腺非组蛋白染色体蛋白HMG-1和HMG-2的N端序列进行了比较。两者的N端序列均呈碱性,仅在一个位置上有所不同。这与我们之前所表明的HMG-1的C端部分富含酸性残基形成对比。与任何已知的组蛋白序列均无明显的序列同源性。
