One class of these enzymes is classified by a DEAD box motif within a Walker B domain, and the Droso
One class of these enzymes is classified by a DEAD box motif within a Walker B domain, and the Drosophila protein Twister is a homolog of another one of these enzymes found in yeast, Ski2. Another one of them responsible for initiating repairs is RecQ, while Werner's syndrome is caused by a mutation in another one of them. Other examples of these enzymes include the E. coli DnaB and the gp4 protein encoded by the T7 phage. Many of these enzymes appear as a ring-shaped hexamer that also contains an N-terminal primase domain. During replication, they hydrolyze ATP to move the replication fork forward. FTP, name these proteins that unwind DNA.
