Amino-acid and carbohydrate compositions in addition to limited NH2-terminal sequence data of four preparations of HLA antigens, including products of both of the major histocompatibility loci (HLA-A and HLA-B), show that the antigens have great homology in the primary structure. A striking observation is that HLA antigens also have a considerable structure homology with mouse H-2 antigens. HLA antigens appear to have one carbohydrate side chain which has the same composition in all four cases. The possible relation of the structure of the heavy chain of HLA antigens to immunoglobulins is discussed, based on the limited data which are available so far.
除了四种HLA抗原制剂(包括两个主要组织相容性位点HLA - A和HLA - B的产物)的有限氨基末端序列数据外,氨基酸和碳水化合物组成表明这些抗原在一级结构上具有高度同源性。一个显著的观察结果是,HLA抗原与小鼠H - 2抗原在结构上也有相当的同源性。HLA抗原似乎有一个碳水化合物侧链,在所有四种情况下其组成相同。基于目前可用的有限数据,讨论了HLA抗原重链结构与免疫球蛋白的可能关系。
