Current studies on histone ubiquitination require the development of more effective
approaches for the preparation of ubiquitinated histones. Here, we report a new approach
to obtain ubiquitinated histone mimics by using a thioether linkage. The synthetic
ubiquitinated histone mimic is stable under reducing conditions and has the same atom
number as the native structure. Biochemical experiments showed that the mimic is a
good surrogate for natural ubiquitinated histone.
