Fig. 1From: Screening and evolution of a novel protist xylose isomerase from the termite Reticulitermes speratus for efficient xylose fermentation in Saccharomyces cerevisiae Phylogenetic tree. Phylogenetic analysis based on the amino acid sequences of the clones isolated in this study (bold) and other known XIs. Organism sources were selected based on their functional expression in S. cerevisiae (underlined) and sequence similarity. Protein names or protein accession numbers are givenBack to article page
