Pectin Lyase PelB-GFP

This Pectin Lyase is a protein from Paenibaciullus amylolyticus. With Pnl and PelC, PelB is able to cleave and therefore breakdown pectin or homogalacturonan substrates. This protein has been characterized to cleave methylated pectin (at unmethylated sites) and polygalacturonic acid. Studies by Keggi and Doran-Peterson, PelB has a Km of 50.1+/- 140 mg/ml and a Vmax of 745 +/-2024 IU/mg with a 80% methylated substrate. The optimal temperature for PelB activity was determined to be 70°C [1].

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