Optimization of the high-level production of Rhizopus oryzae lipase in Pichia pastoris.

TL;DR: The lipases of the Rhizopus species family are important and versatile enzymes that are mainly used in fat and oil modification due to their strong 1,3-regiospecificity and could be further increased by introducing a transition phase that involved the simultaneous feeding of glycerol and methanol followed by a single meethanol feed.
Journal ArticleDOI

Functional expression of Rhizopus oryzae lipase in Pichia pastoris: high-level production and some properties

TL;DR: Recombinant ROL lipase was purified to homogeneity by a simple two-step purification procedure and had a specific activity of 8571 U mg-1 (triolein, 30 degrees C, pH 8.1) which is comparable with the purified native enzyme.
Journal ArticleDOI

Designing new metal affinity peptides by random mutagenesis of a natural metal-binding site

TL;DR: The metal-binding site of a Helicobacter pylori ATPase 439 (heli(WT)-tag) was successfully used as a new fusion peptide for immobilized metal ion affinity chromatography (IMAC) and produced higher yields than the frequently used his6-tag.
Journal ArticleDOI

Determination of peracid and putative enzymatic peracid formation by an easy colorimetric assay

TL;DR: In this paper, a semi-quantitative colorimetric method for the determination of peracids in the presence of hydrogen peroxide in Luria-Bertani agar is described.
