Protein

Salutaridinol 7-O-acetyltransferase

Gene
SALAT
Organism
Papaver somniferum (Opium poppy)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

Functioni

Catalyzes the conversion of the phenanthrene alkaloid salutaridinol to salutaridinol-7-O-acetate, the immediate precursor of thebaine along the morphine biosynthetic pathway. Conversion of 7-O-acetylsalutaridinol into thebaine is spontaneous.1 Publication

Catalytic activityi

Acetyl-CoA + salutaridinol = CoA + 7-O-acetylsalutaridinol.1 Publication

Kineticsi

  1. KM=9 µM for salutaridinol1 Publication
  2. KM=54 µM for acetyl-CoA

Vmax=25 pmol/sec/mg enzyme

pH dependencei

Optimum pH is 7-9.

Temperature dependencei

Optimum temperature is 47 degrees Celsius.
