>gnl|CDD|143601 cd07577, Ph0642_like, Pyrococcus horikoshii Ph0642 and related proteins, members of the nitrilase superfamily (putative class 13 nitrilases). Uncharacterized subgroup of the nitrilase superfamily. This superfamily is comprised of nitrile- or amide-hydrolyzing enzymes and amide-condensing enzymes, which depend on a Glu-Lys-Cys catalytic triad. Pyrococcus horikoshii Ph0642 is a hypothetical protein belonging to this subgroup. This superfamily has been classified in the literature based on global and structure based sequence analysis into thirteen different enzyme classes (referred to as 1-13). This subgroup was classified as belonging to class 13, which represents proteins that at the time were difficult to place in a distinct similarity group. Members of this superfamily generally form homomeric complexes, the basic building block of which is a homodimer. Length = 259
