Pig heart lipoamide dehydrogenase was crystallized by the hanging-drop vapor-diffusion method. X-ray diffraction patterns show that the hexagonal crystals have unit-cell dimensions of a = b = 359. 3, c = 140.5 A. The crystal structure has been preliminarily solved by the molecular-replacement method in the space group P6322. Three dimeric molecules have been found in the asymmetric unit, one of them located on the crystallographic twofold axis.
采用悬滴气相扩散法使猪心硫辛酰胺脱氢酶结晶。X射线衍射图谱表明，六方晶体的晶胞参数为a = b = 359.3 Å，c = 140.5 Å。晶体结构已通过分子置换法在空间群P6322中初步解析。在不对称单元中发现了三个二聚体分子，其中一个位于晶体学二重轴上。
