由于氨基酸的限制，金黄色葡萄球菌RN6390在牛奶中呈现双向生长。寡肽渗透酶Opp3(专用于菌株的氮素营养)的失活不仅影响菌株的生长，还导致三种主要胞外蛋白酶的表达水平下降。
Staphylococcus aureus RN6390 presents a diauxic growth in milk, due to amino acid limitation. Inactivation of the oligopeptide permease Opp3 (dedicated to the nitrogen nutrition of the strain) not only affects the growth of the strain but also results in reduced expression levels of three major extracellular proteases.
