evolution | specific Archaea such as Sulfolobus tokodaii have retained ArcS in addition to GAT-QueC, overview | Sulfurisphaera tokodaii |
metabolism | GAT-QueC also catalyzes biosynthesis of G+-tRNA, pathways, overview | Sulfurisphaera tokodaii |
additional information | G+ can be tolerated in Escherichia coli at position 34 in normally Q-containing tRNA when recombinant GAT-QueC and QueF are introduced | Euryarchaeota |
physiological function | ArcS catalyzes the final step in the G+ pathway, the conversion of preQ0-tRNA to G+-tRNA, in Euryarchaeota | Sulfurisphaera tokodaii |
