Table 1 Estimation of the numbers of conventional CCCH motifs in protozoa and yeast.

From: Genome-wide in silico screen for CCCH-type zinc finger proteins of Trypanosoma brucei, Trypanosoma cruzi and Leishmania major

  1. The genomes of the organisms listed were searched for the two conventional CCCH motifs and in addition for two fantasy CCCH motifs (C-X7-C-X7-C-X3-H and C-X8-C-X7-C-X3-H). No filtering steps were performed. The total number of conventional CCCH motifs was estimated by adding the numbers of the two conventional CCCH motifs and subtracting the numbers of the two fantasy CCCH motifs.
