The zinc hydrolase histone deacetylase 6 (HDAC6) is unique among vertebrate deacetylases in that it contains two catalytic domains, designated CD1 and CD2. Both domains are fully functional as lysine deacetylases in vitro. However, the in vivo function of only the CD2 domain is well defined, whereas that of the CD1 domain is more enigmatic. Three X-ray crystal structures of HDAC6 CD1-inhibitor complexes are now reported to broaden the understanding of affinity determinants in the active site. Notably, cocrystallization with inhibitors
