RNA helicases are indispensable for all organisms in each domain of life and
have implications in numerous cellular processes. The DEAH-box RNA helicase
Prp43 is involved in pre-mRNA splicing as well as rRNA maturation. Here, the
crystal structure of Chaetomium thermophilum Prp43 at 2.9 Å resolution is
revealed. Furthermore, it is demonstrated that Prp43 from C. thermophilum is
capable of functionally replacing its orthologue from Saccharomyces cerevisiae
in spliceosomal disassembly assays.
