Figure 2From: Dynamic evolution of selenocysteine utilization in bacteria: a balance between selenoprotein loss and evolution of selenocysteine from redox active cysteine residuesPhylograms of SelA, SelB, and FdhA sequences from Alphaproteobacteria, Betaproteobacteria, and Gammaproteobacteria. Organisms and phyla are shown by different colors. Red indicates Alphaproteobacteria, blue indicates Betaproteobacteria, green indicates Gammaproteobacteria/Pseudomonadales, and pink indicates other Gammaproteobacteria. In the FdhA phylogram, U represents Sec-containing sequences and C Cys-containing sequences.Back to article page
