Cytochromes c are proteins that can be defined both phenotypically and by their possession of a characteristic sequence motif. Many sequences from bacterial sources are known, and new ones are being reported every year. An analysis can be made as to what fraction of new sequences are members of already known classes or subclasses, and how many map into previously uninhabited regions of sequence space.
细胞色素c是一类蛋白质，既可以通过表型来定义，也可以根据其具有的特征序列基序来定义。已知许多来自细菌的序列，并且每年都有新的序列被报道。可以分析新序列中有多少是已知类别或亚类的成员，以及有多少映射到序列空间中以前未被占据的区域。
