LolA Protein, E.coli (P.pastoris, His)
LolA Protein translocates lipoproteins from bacterial inner to outer membranes, forming a complex dependent on the absence of aspartate after the N-terminal cysteine. Aspartate signals lipoproteins to stay in the inner membrane. LolA, as a monomer, efficiently moves lipoproteins between bacterial membrane compartments. LolA Protein, E.coli (P.pastoris, His) is the recombinant E. coli-derived LolA protein, expressed by P. pastoris , with N-His labeled tag.

Biological Activity
Description
LolA Protein translocates lipoproteins from bacterial inner to outer membranes, forming a complex dependent on the absence of aspartate after the N-terminal cysteine. Aspartate signals lipoproteins to stay in the inner membrane. LolA, as a monomer, efficiently moves lipoproteins between bacterial membrane compartments. LolA Protein, E.coli (P.pastoris, His) is the recombinant E. coli-derived LolA protein, expressed by P. pastoris , with N-His labeled tag.
Background
LolA Protein is involved in the translocation of lipoproteins from the inner membrane to the outer membrane in bacterial cells. It forms a complex with lipoproteins, but this interaction is contingent upon the absence of aspartate immediately following the N-terminal cysteine in the lipoprotein sequence. The presence of aspartate serves as a targeting signal, indicating that the lipoprotein should remain in the inner membrane. LolA functions as a monomer in facilitating the efficient movement of lipoproteins between bacterial membrane compartments.
