Enzymes
Display Intricacy in Repackaging DNA
For almost a half century, methylation of DNA-binding histones was thought to
be irreversible. Two years ago, Yang Shi and colleagues discovered an enzyme
that could remove a methyl group from histones bearing two such groups. Now,
Johnathan Whetstine, Shi, Monica Colaiacovo (right to left), and colleagues report
that they have uncovered a whole family of enzymes that are capable of stripping
methyl groups not from dimethylated, but from trimethylated histones. Histone
modifications like these are increasingly seen as playing a role in cancer and
other diseases.
