Yeast (Saccharomyces cerevisiae) SWI/SNF is a prototype for a large family of ATP-dependent chromatin-remodeling enzymes that facilitate numerous DNA-mediated processes. Swi2/Snf2 is the catalytic subunit of SWI/SNF, and it is the founding member of a novel subfamily of the SF2 superfamily of DNA helicase/ATPases. Here we present a functional analysis of the diagnostic set of helicase/ATPase sequence motifs found within all Swi2p/Snf2p family members. Whereas many of these motifs play key roles in ATP binding and/or hydrolysis, we identify residues within conserved motif V that are specifically required to couple ATP hydrolysis to chromatin-remodeling activity. Interestingly, motif V of the human Swi2p/Snf2p homolog, Brg1p, has been shown to be a possible hot spot for mutational alterations associated with cancers.
