Beschreibung

Allgemeine Beschreibung

Lipase from Rhizopus oryzae (ROL) comprises an oxyanion hole, four N-glycosylation sites, and an active site region. It possesses N-terminal presequence and prosequence.

Research Area: Cell Signaling
Rhizopus oryzae lipase (ROL) is a protein synthesized in a precursor form that includes a presequence of 26 amino acids, followed by a prosequence of 97 amino acids, which is attached to the N-terminal of a mature sequence consisting of 269 amino acids.

Anwendung

Lipase from Rhizopus oryzae has been used:

• to test its effect on 1,2-diolein synthesis and triolein ethanolysis
• for immobilization on graphene oxide support for biocatalysis studies
• to digest triglycerides (TAG) from Chlamydomonas reinhardtii and S. cerevisiae

Lipases are used industrially for the resolution of chiral compounds and the transesterification production of biodiesel.

Biochem./physiol. Wirkung

Rhizopus oryzae lipase (ROL) has been extensively researched for its regiospecificity in biodiesel production. Due to its remarkable characteristics, including 1,3-specificity, high enantioselectivity, and stability in organic solvents, ROL has garnered significant attention for applications in the energy, food, and pharmaceutical industries.

Lipase from Rhizopus oryzae (ROL) acts as a catalyst for the enzymatic biosynthesis of polyglycerol polyricinoleate through a reversal of hydrolysis. ROL is useful in the industrial production of structured lipids due to its 1,3-regiospecificity functionality.

Tri-, Di-, und Monoglyceride sind hydrolysiert (in abnehmender Ratenreihenfolge).
