DEAD-box RNA helicases in Escherichia coli
In spite of their importance in RNA metabolism, the function of DExD/H-box proteins (including DEAD-box proteins) is poorly understood at the molecular level. Here, we present recent progress achieved with the five DEAD-box proteins from Escherichia coli, which have been particularly well studied. These proteins, which have orthologues in many bacteria, participate, in particular, in specific s...
متن کاملDEAD-box RNA helicases in gram-positive RNA decay.
DEAD-box RNA helicases are important players in eukaryotic and bacterial RNA metabolism. A helicase from Staphylococcus aureus was recently shown to affect RNA decay, most likely via its interaction with the proposed Gram-positive degradosome. Some, but not all, RNAs are stabilized when the helicase CshA is mutated, and among the affected RNAs is the agrBDCA mRNA, which is responsible for quoru...
متن کاملComparative Structural Analysis of Human DEAD-Box RNA Helicases
DEAD-box RNA helicases play various, often critical, roles in all processes where RNAs are involved. Members of this family of proteins are linked to human disease, including cancer and viral infections. DEAD-box proteins contain two conserved domains that both contribute to RNA and ATP binding. Despite recent advances the molecular details of how these enzymes convert chemical energy into RNA ...

متن کاملVasa-Like DEAD-Box RNA Helicases of Schistosoma mansoni
Genome sequences are available for the human blood flukes, Schistosoma japonicum, S. mansoni and S. haematobium. Functional genomic approaches could aid in identifying the role and importance of these newly described schistosome genes. Transgenesis is established for functional genomics in model species, which can lead to gain- or loss-of-functions, facilitate vector-based RNA interference, and...
