A gene which was shown to be cotranscribed with the NAD+-dependent malic enzyme gene (maeE) of Streptococcus bovis ATCC 15352 was revealed to encode L-malate-specific permease (MaeP), which showed high activity at low pHs (pH 5.1 to 5.9). MaeP was strongly inhibited by the ionophores nigericin and valinomycin.
已证明与牛链球菌ATCC 15352的NAD+依赖性苹果酸酶基因(maeE)共转录的一个基因编码L-苹果酸特异性通透酶(MaeP),该通透酶在低pH值(pH 5.1至5.9)下表现出高活性。MaeP受到离子载体尼日利亚菌素和缬氨霉素的强烈抑制。
