Figure . Overview on enzymes potentially involved in the nucleotide salvage pathway of T. maritima. Biocatalysts were identified on the one hand by analyzing the T. maritima specific KEGG pathway (black font color, bold, italic) in comparison to the corresponding reference pathway (gray font color). On the other hand, the T. maritima genome was screened for kinases described in the literature for accepting nucleosides or nucleotides as substrates (blue background). All enzymes marked in bold and italics were expressed, purified and biochemically characterized in this study.
