ProteomicsLC-MS/MS identification of Kbz sites on histones catalyzed by non-enzymatic and enzymatic ways.
Histone lysine benzoylation may occur by Gcn5-catalyzed and nonenzymatically ways in vivo. In this project, we identified several Kbz sites on Xenopus laevis octamer in the absence or presence Gcn5-Ada2 complex in vitro, respectively. The number 672 represents the data in the absence of Gcn5-Ada2, a...

ProteomicsHistone octamer structure is altered early in ISW2 ATP-dependent remodeling of nucleosomes
Histone octamers are thought to be a rigid part of nucleosomes that shape chromatin and block cellular machinery from accessing DNA. ATP-dependent chromatin remodelers like ISW2 mobilize nucleosomes to provide DNA access. We find evidence for histone octamer distortion preceding DNA being moved into...

ProteomicsHistone variant H2A.Z enhances histone and nucleosome dynamics
Interchanging canonical histone H2A with variant H2A.Z in chromatin complexes is vital for the proper regulation of transcription, DNA damage repair, and centromere maintenance. However, the physical mechanisms underlying functional differences between H2A and H2A.Z complexes are unclear. Human H2A ...
