SECIS elements of Caenorhabditis Sec-containing thioredoxin reductase. (A) C. brenneri, (B) C. briggsae, (C) C. elegans, (D) C. japonica, (E) C. remanei, (F) C. sp5, (G) C. sp11. All Caenorhabditis encode a type I SECIS element with a guanine immediately upstream of the non-Watson-Crick base-pairing quartet. The non-Watson-Crick base-pairing quartet (SBP2-binding site) and the AAR triplet are highlighted.
