Alginate lyase algL is an enzyme found in Pseudomonas aeruginosa. It is a 40 kDA poly-β-D-mannuronate lyase. AlgL degradates heteropolymer of β-D-mannuronate (M) and α-L-guluronate (G) that constitutes alginate. As alginate is the most abundant extracellular polysaccharide of the Pseudomonas aeruginosa PA01biofilm matrix, it has been shown that algL degradates PA01’s biofilm via β elimination. The gene coding for this enzyme has been cloned into pUCBB BBa_K3463000 and expressed in DH5 alpha Escherichia coli. Source of the part: Genomic extraction by PCR on Pseudomonas aeruginosa PAO1.

Design considerations: AlgL is regulated by AlgB in Pseudomonas aeruginosa genome. Should be added if production in E. coli is insufficient. Biosynthesis is higher when in presence of high salt concentrations.
