Abstract
MtrC and OmcA are cell surface-exposed lipoproteins important for reducing solid metal oxides. Deletions of type II secretion system (T2SS) genes reduced their extracellular release and their accessibility to the proteinase K treatment, demonstrating the direct involvement of T2SS in translocation of MtrC and OmcA to the bacterial cell surface.
摘要
MtrC和OmcA是细胞表面暴露的脂蛋白，对还原固体金属氧化物很重要。II型分泌系统（T2SS）基因的缺失减少了它们的细胞外释放以及它们对蛋白酶K处理的可及性，表明T2SS直接参与了MtrC和OmcA转运至细菌细胞表面的过程。
