Cloned(Commentary)

EC Number Cloned (Comment) Organism
2.3.1.20 gene YALI0_E32769g, sequence comparisons, recombinant expression of MBP-tagged wild-type enzyme and mutants in Escherichia coli strain BL21(DE3) pLysS Yarrowia lipolytica

Protein Variants

EC Number Protein Variants Comment Organism
2.3.1.20 additional information construction of enzyme mutants Dga1pDELTA19, lacking a region predicted to be disordered, and Dga1pDELTA85, lacking the 85 N-terminal residues predicted to contain a transmembrane domain. Mutant Dga1pDELTA19 shows reduced activity compared to wild-type, while mutant Dga1pDELTA85 is inactive Yarrowia lipolytica

Inhibitors

EC Number Inhibitors Comment Organism Structure
2.3.1.20 niacin a specific noncompetitive DGAT2 inhibitor. Dga1p enzyme mutant versions exhibit DGAT2 specific activity, which is inhibited by niacin. The decrease is 70% for Dga1pDELTA19 and up to 99.5% for Dga1pDELTA85 Yarrowia lipolytica

2.3.1.20 additional information acyl-CoA substrate specificity analysis of wild-type and mutant enzymes, overview. Dga1p enzymes can integrate saturated substrates of different length. Dga1p prefers long chain saturated acyl-CoAs as acyl donors in vitro. Also mutant Dga1pDELTA85 is less efficiently with the C12:0-CoA substrate than with longer substrates Yarrowia lipolytica ?
