Abstract

The sequence corresponding to the mature lipase of Rhizopus oryzae WPG (ROLw) was subcloned in the pPIC9K expression vector, with a strong AOX1 promoter, to construct a recombinant lipase protein containing six histidine residues at the N-terminal. The His-tagged lipase was expressed in Pichia Pastoris X33 and purified to homogeneity by a simple, one-step purification protocol using immobilized metal affinity chromatography (Ni-NTA resin). High level expression of the lipase by Pichia Pastoris X33 cells harbouring the lipase gene containing expression vector was observed upon induction with 2.5 g/l methanol at 28°C; the specific activity of the purified His6-ROLw was 1,500 or 760 U/mg using olive oil emulsion or tributyrin as substrates, respectively. To check the importance of Asn 134 His substitution in the affinity and substrate selectivity of ROLw, the mutant His6-ROLw-N134H was overexpressed in Pichia Pastoris X33 and purified with the same nickel metal affinity column. The specific activity of the purified His-tagged ROLw-N134H was 5,900 and 35 U/mg using olive oil emulsion or tributyrin as substrate. A comparative study of the wild type (His6-ROLw) and the mutant (His6-ROLw-N134H) proteins was carried out. A 3D structure model of ROLw was built using the RNL structure as template. We have concluded that a slight increase in the exposed hydrophilic residues on the surface of ROLw as compared to RNL (ROLwN134H) could be responsible for a higher selectivity of ROlw for long and short chain triacylglycerols at the lipid/water interface and then explaining the importance of Asn 134 for the chain length specificity of ROLw. This property is quite rare among Rhizopus lipases and gives this new lipase great potential for use in the field of biocatalysis.
