The complete amino acid sequence of cytochrome c-552 from an extremely thermophilic hydrogen bacterium, Hydrogenobacter thermophilus TK-6 (IAM 12695), was determined. It is a single polypeptide chain of 80 residues, and its molecular weight, including heme, was calculated to be 7,599. The sequence of cytochrome c-552 from H. thermophilus TK-6 closely resembles that of cytochromes c-551 from Pseudomonas species. Moreover, the tertiary structure of Hydrogenobacter cytochrome c-552 is suggested to be similar to that of cytochrome c-551 from Pseudomonas aeruginosa. The sequence similarity between Hydrogenobacter cytochrome c-552 and that of other bacteria physiologically related to H. thermophilus is not high.
测定了嗜热氢细菌嗜热栖热菌TK - 6(IAM 12695)细胞色素c - 552的完整氨基酸序列。它是一条由80个残基组成的单多肽链,包括血红素在内,其分子量经计算为7599。嗜热栖热菌TK - 6的细胞色素c - 552序列与假单胞菌属的细胞色素c - 551序列极为相似。此外,嗜热栖热菌细胞色素c - 552的三级结构被认为与铜绿假单胞菌的细胞色素c - 551相似。嗜热栖热菌细胞色素c - 552与其他在生理上与嗜热栖热菌相关的细菌之间的序列相似性并不高。
