Abstract
Clostridium botulinum type G produces a toxin complex that is composed of neurotoxin, hemagglutinin, and nontoxic nonhemagglutinin. The three genes encoding these proteins were closely linked on a plasmid of about 114 kb (76 MDa) but not on chromosomal DNA. In contrast to the genes of other C. botulinum serotypes, the genes encoding type G toxin are on a plasmid.
摘要
G型肉毒梭菌产生一种毒素复合物，该复合物由神经毒素、血凝素和无毒非血凝素组成。编码这些蛋白质的三个基因紧密连锁在一个约114 kb（76 MDa）的质粒上，而不在染色体DNA上。与其他肉毒梭菌血清型的基因不同，编码G型毒素的基因位于质粒上。
