Protein
ATP-dependent DNA helicase UvrD2
Organism
Mycobacterium tuberculosis (strain CDC 1551 / Oshkosh)
Function
DNA-dependent ATPase, stimulated equally by ss-and dsDNA. Has both ATPase and helicase activities, and translocates along ssDNA displacing bound streptavidin. Its essentiality for growth does not depend on its helicase activity (By similarity).
Similarity
Belongs to the helicase family. UvrD subfamily.
