Protein SRP19 is an important component of the signal recognition particle (SRP) as it promotes assembly of protein SRP54 with SRP RNA and recognizes a tetranucleotide loop. Structural features and RNA binding activities of SRP19 of the hyperthermophilic archaeonArchaeoglobus fulgiduswere investigated. An updated alignment of SRP19 sequences predicted three conserved regions and two α-helices. With Af-SRP RNA the Af-SRP54 protein assembled into anA. fulgidusSRP which remained intact for many hours. Stable complexes were formed between Af-SRP19 and truncated SRP RNAs, including a 36-residue fragment representing helix 6 ofA. fulgidusSRP RNA.
