Crustacean hyperglycemic hormone (CHH) was isolated from sinus glands of Carcinus maenas, and its primary structure was determined by manual microsequencing, using the DABITC-PITC double-coupling method. The neurohormone consists of 72 amino acid residues (8524 Da). Three disulfide bridges are present and both the N- and C-terminus are blocked. CHH does not show significant sequence homology to any known peptide hormone or protein.
从绿青蟹的窦腺中分离出了甲壳类高血糖激素(CHH),并采用DABITC-PITC双偶联法通过手动微量测序确定了其一级结构。这种神经激素由72个氨基酸残基组成(8524道尔顿)。存在三个二硫键,N端和C端均被封闭。CHH与任何已知的肽激素或蛋白质均无明显的序列同源性。
