The putative fumarylacetoacetase TTHA0809 from T. thermophilus HB8 has been overexpressed, purified and crystallized. The crystals diffracted X-rays to 2.2 Å resolution using synchrotron radiation. Fumarylacetoacetase catalyzes the final step of tyrosine and phenylalanine catabolism. A recombinant form of the fumarylacetoacetase family member TTHA0809 from Thermus thermophilus HB8 has been crystallized by the oil-microbatch method using sodium chloride as a precipitating agent. The crystals belong to the monoclinic space group P2{sub 1}, with unit-cell parameters a = 93.3, b = 73.4, c = 122.6 Å, β = 111.8°. The crystals are most likely to contain two dimers in the asymmetric unit, with a V{sub M} value of 3.32 Å{sup 3} Da{sup −1}. Diffraction data were collected at 2.2 Å resolution using synchrotron radiation at beamline BL26B1 of SPring-8, Japan.
