Cluster based on sequence comparison of homologous proteins of 95 organism species

Data detail

info Data name Cluster based on sequence comparison of homologous proteins of 95 organism species
info DOI 
info Description of data contents 

Clustering was performed by the method in which the round-robin BLAST search of the above amino acid sequence data is performed, the E-value and the overlap score (the All-against-all BLASTP search of the above amino acid sequence data, and heuristic estimation of a similarity threshold for homologs of each protein by entropy-optimized organism count method (Bioinformatics 2009 Mar 1;25(5):599-605.). The data are given in a CSV format text file.
