Erwinicin, produced by Erwinia aroideae cells, consists of rod-shaped particles. The molecular weight of such particles, determined by the method of sedimentation in saccharose gradient, is 15 megadaltons. The size of the particles is 14 x 160 nm. The preparations of erwinicin are thermolabile, insensitive to the action of RNAase, pronase, DNAase and possess antigenic properties. The synthesis of erwinicin is an inducible process.
由软腐欧文氏菌细胞产生的欧文菌素由杆状颗粒组成。通过蔗糖梯度沉降法测定，这些颗粒的分子量为15兆道尔顿。颗粒大小为14×160纳米。欧文菌素制剂对热不稳定，对核糖核酸酶、链霉蛋白酶、脱氧核糖核酸酶的作用不敏感，并具有抗原特性。欧文菌素的合成是一个诱导过程。
