Abstract

The lipoteichoic acid in Staphylococcus aureus growing at high pH values contained very little alanine ester, showing that high overall levels of substitution were not essential for growth. The low alanine content could have resulted from a progressive loss due to base-catalyzed hydrolysis of the labile ester linkages.

摘要

在高pH值下生长的金黄色葡萄球菌中的脂磷壁酸含有的丙氨酸酯很少,这表明高总体取代水平对于生长并非必不可少。低丙氨酸含量可能是由于不稳定酯键的碱催化水解导致的逐渐损失。
