mppp
Description Arginine 4-hydroxylase/deaminase (1.13.12.-)
Alternative names MppP (gene name);
RohP (gene name)
Catalyzed reaction L-arginine + 2O(2)+2H(2)O = (S)-4-hydroxy-2-ketoarginine + H(2)O(2)
Cofactor Pyridoxal phosphate
Comments The enzyme from S. waydamensis is involved in the Enduracididine Biosynthetic Pathway.
It yields a mixture of 2-oxo-4-hydroxy-5-guanidinovalerate and 2-oxo-5-guanidinovalerate in a 1.7:1 ratio.
