Yersinia enterocolitica is a bacterium that causes a variety of clinical and immunological manifestations in humans, mainly through contaminated food or water . This species has seven biotypes (1A, 1B, 2, 3, 4, 5, and 6) and more than 60 serotypes, with certain serotypes (O3; O5,27; O8; and O9) being more prevalent in human isolates . Y. enterocolitica includes strains with varying degrees of pathogenicity: nonpathogenic (biotype 1A), weakly pathogenic (biotypes 2 to 6), and highly pathogenic strains (biotype 1B) . The high pathogenicity of biotype 1B is linked to the yersiniabactin siderophore-mediated iron uptake system .

The arnC gene encodes Undecaprenyl-phosphate 4-deoxy-4-formamido-L-arabinose transferase, also known as Ara4FN transferase . This enzyme is involved in the biosynthesis of lipid A, a component of lipopolysaccharide (LPS) in Yersinia enterocolitica . LPS is a major constituent of the outer membrane of Gram-negative bacteria and plays a crucial role in the bacteria's resistance to antimicrobial peptides and other environmental factors .
Yersinia enterocolitica biotype 1B strains are highly pathogenic, and their virulence is associated with specific genes and pathways . The arnC gene and its product, Undecaprenyl-phosphate 4-deoxy-4-formamido-L-arabinose transferase, contribute to the modification of lipid A, which can affect the bacterium's resistance to antimicrobial peptides . Modification of lipid A can alter the charge and structure of the bacterial surface, reducing the binding and activity of antimicrobial peptides .
Molecular characterization of Y. enterocolitica isolates is important for understanding their epidemiology and virulence . Techniques such as pulsed-field gel electrophoresis (PFGE) are used to analyze the genetic relatedness of different isolates . The presence and expression of virulence genes, including those involved in LPS biosynthesis, are also examined to determine the pathogenic potential of the bacteria .
This enzyme catalyzes the transfer of 4-deoxy-4-formamido-L-arabinose from UDP to undecaprenyl phosphate. The modified arabinose is incorporated into lipid A, contributing to resistance against polymyxin and cationic antimicrobial peptides.
