Abstract

To help understand the molecular mechanisms of Pasteurella multocida toxin (PMT) action, we searched for a cellular protein interacting with PMT. The ligand overlay assay revealed a 60-kDa cellular protein that binds to a region from the 840th to 985th amino acids of the toxin. This protein was identified as vimentin by peptide mass fingerprinting. The N-terminal head domain of vimentin was further found to be responsible for the binding to the toxin.

摘要

为了帮助理解多杀巴斯德菌毒素(PMT)作用的分子机制,我们寻找了一种与PMT相互作用的细胞蛋白。配体覆盖分析揭示了一种60 kDa的细胞蛋白,它与毒素第840至985个氨基酸区域结合。通过肽质量指纹图谱鉴定该蛋白为波形蛋白。进一步发现波形蛋白的N端头部结构域负责与毒素的结合。
