  ABSTRACT  
 
Histone deacetylases (HDACs) regulate chromatin status and gene expression, and their inhibition is of significant therapeutic interest. To date, no biological substrate for class IIa HDACs has been identified, and only low activity on acetylated lysines has been demonstrated. Here, we describe inhibitor-bound and inhibitor-free structures of the histone deacetylase-4 catalytic domain (HDAC4cd) and of an HDAC4cd active site mutant with enhanced enzymatic activity toward acetylated lysines. The structures presented, coupled with activity data, provide the molecular basis for the intrinsically low enzymatic activity of class IIa HDACs toward acetylated lysines and reveal active site features that may guide the design of class-specific inhibitors. In addition, these structures reveal a conformationally flexible structural zinc-binding domain conserved in all class IIa enzymes. Importantly, either the mutation of residues coordinating the structural zinc ion or the binding of a class IIa selective inhibitor prevented the association of HDAC4 with the N-CoR.HDAC3 repressor complex. Together, these data suggest a key role of the structural zinc-binding domain in the regulation of class IIa HDAC functions.

FIGURE 4. Interactions of HDAC4cd with inhibitors. A, interactions of the TFMK (yellow carbons) and HA (green carbons) with HDAC4; the complex structures have PDB codes 2VQJ and 2VQM, respectively. Red spheres, water molecules. The surface around the protein is shown for the TFMK-bound HDAC4cd. B, superposition of HDAC4cd (cyan) bound to TFMK (sticks and surface) with HDAC8 (yellow) and homology-modeled HDAC1 (magenta). Residues surrounding the trifluoro group are labeled. Cyan spheres, C atoms.

FIGURE 5. The active sites of HDAC4 and HDAC8. A, the active site of HDAC8 (yellow side chains) bound to a hydroxamic acid inhibitor (light brown) from Protein Data Bank entry 1W22 [PDB] . B, WT HDAC4cd with bound TFMK (yellow carbons) (Protein Data Bank code 2VQQ) and superposed HA (green carbons) (Protein Data Bank code 2VQM). The active site closely resembles HDAC8. C, the active site of GOF HDAC4cd with HA bound (Protein Data Bank code 2VQV); Tyr^976 adopts the inward, class I-like conformation. D, the active site of GOF HDAC4cd with TFMK bound (Protein Data Bank code 2VQO); Tyr^976 adopts an outward conformation.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
