A larger-molecular-weight precursor of enterotoxin A was found in membranes of Staphylococcus aureus and was shown to be the kinetic precursor to the extracellular form of the toxin. Subcellular fractionation revealed that mature enterotoxin A was transiently associated with the cell wall before being released to the extracellular environment.

在金黄色葡萄球菌的细胞膜中发现了一种分子量更大的肠毒素A前体，并证明它是该毒素细胞外形式的动力学前体。亚细胞分级分离显示，成熟的肠毒素A在释放到细胞外环境之前与细胞壁短暂结合。
