Phenylalanyl-tRNA synthetase (EC 6.1.1.20) from the extreme thermophile Thermus thermophilus HB8 has been crystallized with its cognate tRNA. Compared with the native crystals, the crystals of the complex are more stable to radiation damage and diffract to 3.0 A resolution. They are of space group P3(2)21, with a = b = 175 A, c = 142.1 A, gamma = 120 degrees, almost identical with the crystal parameters of the native synthetase.
来自嗜热栖热菌HB8的苯丙氨酰-tRNA合成酶（EC 6.1.1.20）已与其同源tRNA一起结晶。与天然晶体相比，复合物晶体对辐射损伤更稳定，衍射分辨率达到3.0埃。它们属于空间群P3(2)21，a = b = 175埃，c = 142.1埃，γ = 120°，与天然合成酶的晶体参数几乎相同。
