Pectin Lyase PelC-GFP

The PelC Pectin Lyase is originally from Paenabacillus amylolyticus. This particular pectin lyase is more specific to methylated pectin or homogalacturonan substrates rather than polygalacturonic acid [1]. This protein also works with both PelB (BBa_K3349001) and Pnl (BBa_K3349001) in this organism to effectively break down pectin. PelC has an optimal activity at 55°C and a pH of 10. The Km in in terms of 80% methylated substrates is 0.41 +/-0.06mg/ml. Calcium is a cofactor for this protein and is therefore necessary within the buffer conditions [1].

A GFP reporter was added onto the C-terminus. As well a C-terminal his tag was added to the GFP for nickel affinity purification.

For more information on our design and use please see our webpage https://2020.igem.org/Team:Lethbridge_HS or visit the PelC gene part page BBa_K3349002.

Figure 1: Restriction digest of PelB and PelC DNA from the pUC57 plasmid using EcoRI and PstI enzymes run on a 1% agarose gel. The red boxes show the band corresponding to that of our DNA constructs. PelC-GFP in lane 4 shows similar results as well as an unexpected band at around 1500bp. While double checking our construct designs we noticed a illegal EcoRI cut site in the coding sequence that was missed during initial designing.
