The sequence of the first 25 residues of the homoserine dehydrogenase fragment, produced by limited proteolysis of aspartokinase I-homoserine dehydrogenase I with substilisin, has been determined. The sequence of a cyanogen bromide peptide (CB5, 59 residues), isolated from the entire protein, is also presented. Residues 1 to 18 of the subtilisin homoserine dehydrogenase fragment match the sequence 42 to 59 of peptide CB5.
已确定用枯草杆菌蛋白酶对天冬氨酸激酶I-高丝氨酸脱氢酶I进行有限蛋白酶解所产生的高丝氨酸脱氢酶片段前25个残基的序列。还给出了从完整蛋白质中分离出的溴化氰肽(CB5,59个残基)的序列。枯草杆菌蛋白酶高丝氨酸脱氢酶片段的第1至18个残基与肽CB5的第42至59个序列匹配。
