Results of HHpred searches of the SCOP25 database with histone sequences and C-domains. The relative frequencies of SCOP families encountered in the searches are plotted against the HHpred probabilities as described in the Methods (searches with histones – top panel; searches with C-domains – bottom panel). Histones (SCOP a.22) are colored in green, C-domains (SCOP c.37.1.20; also includes the misclassified a.49.1.1) in blue, Clp N-domains (SCOP a.174) in red and others in gray.
