For Saccharomyces cerevisiae, loss of a single H4-specific histone acetyltransferase (HAT), Esa1p, results in cell cycle defects and death. In contrast, although several yeast HAT complexes preferentially acetylate histone H3, the catalytic subunits of these complexes are not essential for viability. To resolve the apparent paradox between the significance of H3 versus H4 acetylation, we tested the hypothesis that H3 modification is essential, but is accomplished through combined activities of two enzymes. We observed that TI - Histone H3 specific acetyltransferases are essential for cell cycle progression JF - Genes & Development DO - 10.1101/gad.931401 DA - 2001-12-01 UR - https://www.deepdyve.com/lp/unpaywall/histone-h3-specific-acetyltransferases-are-essential-for-cell-cycle-89XNU0QKRI DP - DeepDyve ER -
