Heterologous expression of Bartonella adhesin A in Escherichia coli by exchange of trimeric autotransporter adhesin domains results in enhanced adhesion properties and a pathogenic phenotype.

abstract：:The lprG-Rv1410c operon is critical for the survival of Mycobacterium tuberculosis during infection, but very little is known about the functions of its proteins. LprG is a lipoprotein, and Rv1410c encodes the major facilitator superfamily small molecule transporter P55. P55 likely exports small molecules outside of t...
