Outer membrane 蛋白 A/OmpA 蛋白, E.coli (His-SUMO)

Outer membrane protein A (OmpA) ensures the structural integrity of the bacterial cell wall and cooperates with TolR to stabilize the peptidoglycan layer. As a porin, OmpA controls the permeability of small solutes. Outer membrane protein A/OmpA Protein, E.coli (His-SUMO) is the recombinant E. coli-derived Outer membrane protein A/OmpA protein, expressed by E. coli , with N-SUMO, N-6*His labeled tag. The total length of Outer membrane protein A/OmpA Protein, E.coli (His-SUMO) is 183 a.a., with molecular weight of ~35.6 kDa.

外膜蛋白 A (OmpA) 在细菌细胞壁的结构完整性中发挥着至关重要的作用，与 TolR 协同作用以维持肽聚糖层在周质中的位置。作为孔蛋白，OmpA 表现出低渗透性，有助于小溶质逐渐渗透其结构。OmpA 内的内门进一步调节溶质的通过，影响分子的选择性运输。此外，OmpA 的重要性还在于它参与与 F 型质粒的接合，它可能作为受体细胞上的重要交配受体，有助于遗传物质的水平转移。
