An amino acid sequence is proposed for the cytochrome c4 from the bacterium Azotobacter vinelandii strain OP. It is a single polypeptide chain of 190 residues, with two sets of haem-attachment cysteine residues at positions 14/17 and 119/122. Proteins with similar sequences are also present in denitrifying pseudomonads. There is similarity in sequence between the two halves of the cytochrome c4 molecule, and each half also shows similarity to the sequences of certain monohaem cytochromes c isolated from organisms that are not obviously closely related to A. vinelandii. Detailed evidence for the amino acid sequence of the protein has been deposited as Supplementary Publication SUP 50125 (17 pages) at the British Library Lending Division, Boston Spa, West Yorkshire LS23 7BQ, U.K., from whom copies are available on prepayment.
已提出来自维涅兰德固氮菌OP菌株的细胞色素c4的氨基酸序列。它是一条由190个残基组成的单多肽链,在第14/17位和119/122位有两组血红素附着半胱氨酸残基。具有相似序列的蛋白质也存在于反硝化假单胞菌中。细胞色素c4分子的两半部分之间存在序列相似性,并且每一半也与从与维涅兰德固氮菌没有明显密切关系的生物体中分离出的某些单血红素细胞色素c的序列相似。该蛋白质氨基酸序列的详细证据已作为补充出版物SUP 50125(17页)存放在英国西约克郡波士顿斯帕LS23 7BQ的大英图书馆出借部,预付款后可从该处获取副本。
