A survey of 10 mycoplasma strains has shown that their capacity to accumulate radioactivity from alpha-methyl-d-glucopyranoside depends on the activity of a phosphoenolpyruvate-dependent phosphotransferase system (PTS), and that this system endows the organisms with a high affinity for glucose as a fermentation substrate. PTS activity was found in Mycoplasma gallisepticum, M. mycoides var. mycoides, and M. mycoides var. capri, but in none of the fermentative Acholeplasma strains nor in some of the nonfermentative Mycoplasma species. Partial characterization of the PTS of M. mycoides var. capri has shown that, like the PTS of Escherichia coli and Staphylococcus aureus, it is strictly dependent on phosphoenolpyruvate as a phosphoryl donor and on componenets of both the cytoplasm and the membrane.
对10株支原体菌株的调查表明，它们从α-甲基-D-吡喃葡萄糖苷积累放射性的能力取决于磷酸烯醇丙酮酸依赖性磷酸转移酶系统（PTS）的活性，并且该系统赋予生物体对作为发酵底物的葡萄糖具有高亲和力。在鸡毒支原体、丝状支原体丝状亚种和丝状支原体山羊亚种中发现了PTS活性，但在任何发酵性无胆甾原体菌株中或在一些非发酵性支原体物种中均未发现。对丝状支原体山羊亚种PTS的部分特性分析表明，与大肠杆菌和金黄色葡萄球菌的PTS一样，它严格依赖磷酸烯醇丙酮酸作为磷酰基供体以及细胞质和细胞膜的成分。
