T7 DNA helicase : ウィキペディア英語版 | T7 DNA helicase T7 DNA helicase is a hexameric motor protein that uses energy from dTTP hydrolysis to process unidirectionally along single stranded DNA, separating the two strands as it progresses. ==Crystal structure== The crystal structure was solved to 3.0 Å resolution in 2000, as shown in the figure. In (A), notice that the separate subunits appear to be anchored through interactions between an alpha helix and an adjacent subunit. In (B), there are six sets of three loops. The red loop, known as loop II, contains three lysine residues and is thought to be involved in binding the ssDNA that is fed through the center of the enzyme.
