This is the C-terminal domain found in GEN1 resolvase. It is composed of three-strand antiparallel beta sheets and four alpha helices [1]. GEN1 protein, a member of the XPG/Rad2 family of structure-selective endonucleases, is specialized for the cleavage of Holliday junction recombination intermediates [2]. Structural comparison indicates that the C-terminal domain is similar to a series of chromobox homology proteins [1]. Functional analysis indicates that the chromodomain provides an additional DNA binding site necessary for efficient HJ cleavage, and its truncation severely hampers GEN1's catalytic activity [3].
