背景信息

**Background of FabD Recombinant Protein**

FabD, encoded by the *fabD* gene, is a key enzyme in bacterial fatty acid biosynthesis. It catalyzes the transacylation of malonyl group from malonyl-CoA to the acyl carrier protein (ACP), forming malonyl-ACP, an essential substrate for fatty acid elongation. This reaction is a critical step in the type II fatty acid synthesis (FAS II) pathway, which is distinct from the mammalian FAS I system and thus represents a potential target for antibacterial drug development.

FabD’s role in bacterial survival and its absence in humans make it an attractive candidate for studying novel antimicrobial agents, particularly against drug-resistant pathogens. Recombinant FabD protein is produced via heterologous expression systems (e.g., *E. coli*) using genetic engineering techniques. Cloning the *fabD* gene into expression vectors allows large-scale production of the purified enzyme for structural, functional, and inhibitory studies.

Research on recombinant FabD has provided insights into its catalytic mechanism, substrate specificity, and interactions with inhibitors. Structural studies, including X-ray crystallography, have revealed its dimeric architecture and active-site residues critical for substrate binding. Additionally, FabD’s conservation across Gram-positive and Gram-negative bacteria underscores its broad relevance in microbial physiology and as a therapeutic target.

Beyond antimicrobial applications, FabD recombinant protein is utilized in synthetic biology and metabolic engineering to modify fatty acid pathways for biofuel or specialty chemical production. Its study also contributes to understanding bacterial resistance mechanisms, such as mutations affecting enzyme-inhibitor interactions. Overall, FabD recombinant protein serves as a vital tool for both basic research and biotechnological innovation.
