[https://www.uniprot.org/uniprot/VPS75_YEAST VPS75_YEAST] Histone chaperone which acts as a cofactor stimulating the histone H3 'Lys-56' acetylation by RTT109. May be involved in vacuolar proteins sorting.<ref>PMID:12134085</ref> <ref>PMID:17320445</ref>

== Publication Abstract from PubMed ==
 +
The histone chaperone Vps75 presents the remarkable property of stimulating the Rtt109-dependent acetylation of several histone H3 lysine residues within (H3-H4)2 tetramers. To investigate this activation mechanism, we determined X-ray structures of full-length Vps75 in complex with full-length Rtt109 in two crystal forms. Both structures show similar asymmetric assemblies of a Vps75 dimer bound to an Rtt109 monomer. In the Vps75-Rtt109 complexes, the catalytic site of Rtt109 is confined to an enclosed space that can accommodate the N-terminal tail of histone H3 in (H3-H4)2. Investigation of Vps75-Rtt109-(H3-H4)2 and Vps75-(H3-H4)2 complexes by NMR spectroscopy-probed hydrogen/deuterium exchange suggests that Vps75 guides histone H3 in the catalytic enclosure. These findings clarify the basis for the enhanced acetylation of histone H3 tail residues by Vps75-Rtt109.
