The enzymes neuraminidase (EC 3.2.1.18) and acylneuraminate pyruvate lyase (EC 4.1.3.3) were found in a strain of vibrio falling into Heiberg's group II isolated from a patient with diarrhea. The neuraminidase of this strain resembles the neuraminidase of Vibrio cholerae. The pH-optimum, activation by Ca-ions and heat inactivation were studied. There is also some indication of an immunologically common antigenicity. The occurrence of this neuraminidase in the Heiberg's group II vibrio stain is discussed especially with reference to the relationship with the well known enzyme of Vibrio cholerae.
在从一名腹泻患者分离出的属于海伯格氏Ⅱ群的一株弧菌中,发现了神经氨酸酶(EC 3.2.1.18)和酰基神经氨酸丙酮酸裂解酶(EC 4.1.3.3)。该菌株的神经氨酸酶类似于霍乱弧菌的神经氨酸酶。研究了其最适pH值、钙离子激活作用和热失活情况。也有一些迹象表明存在免疫共同抗原性。特别参照与霍乱弧菌著名酶的关系,讨论了这种神经氨酸酶在海伯格氏Ⅱ群弧菌菌株中的出现情况。
