Input: Consider Input:  PCC 6803 mutant impaired in cytochrome c maturation .

Output: cytochrome c


Input: Consider Input:  Like the DMA , but unlike all other mammalian class II A genes , the zebrafish gene codes for two cysteine residues which might potentially be involved in the formation of a disulfide bond in the alpha 1 domain .

Output: alpha 1


Input: Consider Input:  This activity creates a 4 - bp staggered cut with 3 ' OH overhangs within a specific sequence of the 21S rRNA gene of omega - strains .


Output: 21S rRNA gene
