This domain is found in ornithine halogenase HalD and related proteins including L-lysine 4-chlorinase BesD and L-lysine 5-chlorinase HalB. In addition to ornithine, HalD chlorinates lysine but with slower rate. This preference of HalD for ornithine is due to a narrower active site pocket [1]. These enzymes are structurally very similar and adopt a typical cupin-like fold.
