Recombinant human PL6 protein, a member of the polysaccharide lyase (PL) family, is an enzyme classically associated with the degradation of complex carbohydrates, particularly alginate—a polysaccharide abundant in brown algae and bacterial biofilms. PL6 enzymes catalyze the cleavage of glycosidic bonds via β-elimination, generating unsaturated oligosaccharides. Structurally, they feature a conserved β-helix fold and catalytic residues (often Arg, Lys, or His) that coordinate the acidic substrate, facilitating proton abstraction and bond cleavage.
Produced using recombinant DNA technology, PL6 is typically expressed in microbial systems (e.g., *E. coli* or yeast) for high purity and scalability. This enables applications in biotechnology, such as biofuel production (converting algal biomass into fermentable sugars), food processing (texture modification), and biomedical research (anti-biofilm agents or anti-inflammatory therapeutics). Its role in alginate metabolism also links it to pathogenic bacteria (e.g., *Pseudomonas*), making it a potential target for antimicrobial strategies.
Recent studies focus on engineering PL6 variants for enhanced stability, substrate specificity, or pH tolerance, leveraging computational modeling and directed evolution. Additionally, its oligosaccharide products exhibit prebiotic and immunomodulatory properties, spurring interest in nutraceuticals. However, challenges remain in optimizing industrial-scale production and understanding its structure-function nuances. PL6’s versatility underscores its significance in green chemistry and biomedical innovation.
