Fusarium oxysporum var. lini (ATCC 10960) formed a facilitated diffusion system for glucose (K(s), about 10 mM) when grown under repressed conditions. Under conditions of derepression, the same system was present together with a high-affinity (K(s), about 40 muM) active system. The maximum velocity of the latter was about 5% of that of the facilitated diffusion system. The high-affinity system was under the control of glucose repression and glucose inactivation. When lactose was the only carbon source in the medium, a facilitated diffusion system for lactose was found (K(s), about 30 mM).
尖孢镰刀菌亚麻变种（ATCC 10960）在受抑制条件下生长时形成了一个葡萄糖易化扩散系统（K(s)，约10 mM）。在去阻遏条件下，该系统与一个高亲和力（K(s)，约40 μM）的活性系统同时存在。后者的最大速度约为易化扩散系统的5%。高亲和力系统受葡萄糖阻遏和葡萄糖失活的调控。当乳糖是培养基中唯一的碳源时，发现了一个乳糖易化扩散系统（K(s)，约30 mM）。
