Phenylalanine to leucine point mutation in oxyanion hole improved catalytic efficiency of Lip12 from Yarrowia lipolytica.


In lipases, oxyanion hole has crucial role in the stabilisation of enzyme-substrate complex. Majority of lipases from Yarrowia lipolytica consist of two oxyanion hole residues viz.; Thr and Leu. However, Lip12 has Phe instead of Leu at second oxyanion hole residue. It was observed that Lip12 has lower specific activity and catalytic efficiency than other… (More)
