植物的超氧化物岐化酶分为Mn、Cu和Zn及Fe酶蛋白同工酶。已有的报道表明大豆种子及叶片中只有7—9条同工酶带,其中A区的同工酶属Mn-SOD,一般有1—3条酶带;B区的同工酶为Cu-Zn-SOD,可分离出3条酶带;C区的同工酶为Cu—Zn—SOD,一般有3条同工酶带。我们在分离大豆SOD同工酶时,
Plant superoxide dismutase is divided into Mn, Cu and Zn and Fe enzyme protein isoenzyme. It has been reported that there are only 7-9 isozyme bands in soybean seeds and leaves, among which isozyme in area A is Mn-SOD, usually 1-3 bands; isozyme in area B is Cu- Zn-SOD, three bands can be isolated; the C-region isoenzyme is Cu-Zn-SOD, generally with three isozyme bands. When we separate soybean SOD isozymes,
