Figure 6From: ANCAC: amino acid, nucleotide, and codon analysis of COGs – a tool for sequence bias analysis in microbial orthologsCorrelation between OGTs and amino acid composition in Archaea. A plot of the OGTs of the Archaeae in the arCOG database versus their (E + K)/(Q + H) ratios is presented confirming the correlation described by Farias and Bonato [12].Back to article page
