Compost Lipase
Comparative Enzyme Activity Assay
Figure 1. Relative Comparaison Lipase Activity Assay. Candida Antarctica Lipase A, Bacillus Subtilis Lipase and Compost Lipase enzyme activity were examined using p-Nitrophenol octanoate as a substrate.
Figure 1 compares enzyme activity of Candida Antarctica Lipase A BBa_K3051001, Bacillus Subtilis Lipase BBa_K3051005 and Compost Lipase BBa_K3051421. The lipase parts were tested and characterized using a p nitrophenol octanoate assay. The enzyme activity was determined by measuring change in light absorbance at a wavelength of 400nm, which directly correlated to the concentration of p-Nitrophenol (pNP), caused by lipolysis of p-Nitrophenol octanoate (pNPO) substrate. The data from the pNPO lipolysis assay defined the enzyme activity.
The lipase was found in a metagenomics search of a compost performed by the University of Gottingen. The enzyme showed 77% identity to Thermostable Lipase A BBa_K258006, and likely conserves a similar function. The conserved domains include a hydrolase site and an RTX toxin related Ca2+ binding site - which could either cause sensitivity to Calcium ions or Calcium ions could act as a cofactor.
Figure 2. CLMP 3D Structure. The protein has a kDa of 64.6 and an estimated molar extinction coefficient of 75290 M-1cm-1 (calculated using ProtoPram ExPaSy tool); the following 3D structure (calculated using Phyre 2).
