Pectin Lyase PelC

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].

For purification purposes, this gene has a C-terminal hexa-histidine tag. For more information on our design and use please see our webpage https://2020.igem.org/Team:Lethbridge_HS.


In the beginning of our project we decided to do homology modelling of our pectin lyase enzymes in order to inform our thermostability modelling.

pnl modelling

Figure 1: Homology modelling of PelC from P. amylolyticus . The protein structure was done using iTASSER [2] and SWISS-Model [3]. The two structures were then aligned and compared. A more in depth analysis can be found on our webpage.
