Transport studies with Penicillium chrysogenum plasma membranes fused with cytochrome c oxidase liposomes demonstrate that sulfate uptake is driven by the transmembrane pH gradient and not by the transmembrane electrical potential. Ca2+ and other divalent cations are not required. It is concluded that the sulfate transport system catalyzes the symport of two protons with one sulfate anion.
用与细胞色素c氧化酶脂质体融合的产黄青霉质膜进行的转运研究表明,硫酸盐的摄取是由跨膜pH梯度驱动的,而不是由跨膜电势驱动的。不需要Ca2+和其他二价阳离子。得出的结论是,硫酸盐转运系统催化两个质子与一个硫酸根阴离子的同向转运。
