The Signal Recognition Particle Database (SRPDB)

The SRPDB (signal recognition particle database) provides annotated SRP RNA sequences from Eucaryotes and Archaea, phylogenetically ordered and aligned with their bacterial equivalents. We also make available representative RNA secondary structure diagrams, where each base pair is proven by comparative sequence analysis. New to this release are 17 SRP RNA sequences (a total of 64 sequences) and alignments of proteins SRP19 and SRP54 with their RNA binding sites.
