背景信息

**Background of YjbL Recombinant Protein**

YjbL is a conserved bacterial protein encoded by the *yjbL* gene, prominently studied in *Escherichia coli* (*E. coli*). It belongs to the DUF1528 protein family, characterized by a conserved domain of unknown function. YjbL is implicated in bacterial stress response pathways, particularly under oxidative stress or during biofilm formation. Studies suggest it interacts with the stationary-phase sigma factor σ^S (RpoS), a global regulator of stress adaptation, though its exact mechanistic role remains under investigation.

Recombinant YjbL protein is produced via genetic engineering, typically by cloning the *yjbL* gene into expression vectors (e.g., pET or pGEX systems) and overexpressing it in host cells like *E. coli*. Purification methods often employ affinity tags (e.g., His-tag) for efficient isolation. The recombinant form enables structural and functional analyses, including crystallography, enzymatic assays, or interaction studies with nucleic acids or partner proteins.

YjbL's potential involvement in biofilm regulation and stress survival makes it a target for antimicrobial research, as disrupting these pathways could weaken bacterial resilience. Additionally, its conserved nature across Gram-negative bacteria highlights its evolutionary significance. Despite progress, gaps persist in understanding its precise biochemical role, driving ongoing research to elucidate its contributions to bacterial physiology and pathogenicity.

In summary, YjbL recombinant protein serves as a critical tool for dissecting bacterial stress adaptation mechanisms and exploring novel therapeutic strategies against biofilm-associated infections.
