Functional Divergence and Conservation in the QueC Protein Family (PF06508): From tRNA Modification to Anti-Phage Defense
{{output}}
The QueC protein family (PF06508) is best known for its role in the biosynthesis of 7‑deazaguanine derivatives, including the tRNA modification queuosine and the DNA base 7‑cyano-7‑deazaguanine (preQ0). Recent discoveries, however, reveal that this ancient ... ...
