Abstract

Metabolic labelling by [14C]palmitic acid showed that growth of Streptococcus mutans LT11 in raffinose, an inducer of the msm operon, resulted in increased production of a 45-kDa lipoprotein corresponding to MsmE, which is believed to be a sugar-binding protein. MsmE was also labelled when an msmE clone was expressed in Escherichia coli. The presence of a lipid anchor on MsmE provides a likely explanation of how the sugar-binding protein component of the msm binding protein-dependent multiple sugar transport system is retained at the cell surface.

摘要

用[14C]棕榈酸进行的代谢标记显示，变形链球菌LT11在棉子糖（msm操纵子的诱导物）中生长，导致产生一种与MsmE相对应的45 kDa脂蛋白，据信它是一种糖结合蛋白。当msmE克隆在大肠杆菌中表达时，MsmE也被标记。MsmE上脂质锚定的存在为msm结合蛋白依赖性多种糖转运系统的糖结合蛋白成分如何保留在细胞表面提供了一个可能的解释。
