snf/swi mutants of S. cerevisiae.

The Saccharomyces cerevisiae Snf/Swi complex has been previously demonstrated to control transcription and chromatin structure of particular genes in vivo and to remodel nucleosomes in vitro酿酒酵母（Saccharomyces cerevisiae）的Snf/Swi复合物此前已被证实可在体内调控特定基因的转录与染色质结构，并可在体外重构核小体。
