Two homologous hydrogen sulfide-producing enzymes, Fn1220 and Cdl, from Fusobacterium nucleatum (which actively produces hydrogen sulfide) were overproduced, purified and crystallized. X-ray diffraction data were collected from the crystals using a synchrotron-radiation source. The Fn1220 crystal belonged to tetragonal space group P4(1)2(1)2 or P4(3)2(1)2 (unit-cell parameters a=b=116.8, c=99.2 A) and the Cdl crystal belonged to monoclinic space group P2(1) (unit-cell parameters a=84.9, b=70.9, c=87.6 A, beta=90.3 degrees ).
