Abstract:
:The SRPDB (signal recognition particle database) provides aligned SRP RNA and protein sequences, annotated and phylogenetically ordered. This release includes 82 SRP RNAs (including 22 bacterial and 9 archaeal homologs) and a total of 20 protein sequences representing SRP9, SRP14, SRP19, SRP54, SRP68, and SRP72. The offerings also include representative RNA secondary structure diagrams.
