Pinoresinol reductase 1

UniProtKB accession:  Q9FVQ6

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Reductase involved in lignan biosynthesis (PubMed:18347017, PubMed:25107662). Involved in secondary cell wall biosynthesis in fiber cells (PubMed:25107662). Unlike conventional pinoresinol reductases that can reduce both pinoresinol and lariciresinol, PRR1 shows a strict substrate preference toward pinoresinol (PubMed:18347017). Active on both (+) and (-)-pinoresinol (PubMed:18347017). Abstracts the 4R-hydride from the NADPH cofactor during catalysis (PubMed:18347017).
