Infective and noninfective strains of Borrelia burgdorferi, along with Borrelia afzelii and Borrelia garinii, possessed a single iron-containing superoxide dismutase (SOD). None of the Lyme disease spirochetes tested possessed catalase or peroxidase activities. The borrelial SOD was not inducible by growth with increased oxygen concentrations and thus appeared to be produced constitutively.
伯氏疏螺旋体的感染性和非感染性菌株,以及阿氏疏螺旋体和伽氏疏螺旋体,都拥有一种含单个铁的超氧化物歧化酶(SOD)。所测试的莱姆病螺旋体均不具有过氧化氢酶或过氧化物酶活性。伯氏疏螺旋体的SOD不会因氧气浓度增加而诱导产生,因此似乎是组成型产生的。
