Figure 1From: Computational identification of a new SelD-like family that may participate in sulfur metabolism in hyperthermophilic sulfur-reducing archaeaOverview of distribution of SelD proteins and Se utilization traits in archaea. The tree is based on 16S rRNA sequences, which was simplified to only show major branches. The numbers of organisms that contain SelD and known Se utilization traits are shown. Distribution of organisms containing SelD-like family is highlighted in red.Back to article page
