Penicillin-binding proteins of 180, 89, 80, 68, 61, 41, and 38 kilodaltons were identified in Treponema pallidum (Nichols) by their covalent binding of [35S]benzylpenicillin. Penicillin-binding proteins are localized in the plasma membranes of many bacterial species and may serve as useful markers for determining plasma membrane intactness in T. pallidum fractionation studies.
通过[35S]苄青霉素的共价结合，在梅毒螺旋体（Nichols株）中鉴定出了分子量分别为180、89、80、68、61、41和38千道尔顿的青霉素结合蛋白。青霉素结合蛋白定位于许多细菌物种的质膜中，在梅毒螺旋体分级分离研究中，可作为确定质膜完整性的有用标记。
