Sarcosine Oxidase from E. coli, Recombinant


Cat No.
DIA-414
Description
Sarcosine oxidase (SAO) is an enzyme that catalyzes the oxidative demethylation of sarcosine to yield glycine, H2O2, 5, 10-CH2-tetrahydrofolate in a reaction requiring H4-tetrahydrofolate and oxygen. sarcosine + H2O + O2 = glycine + formaldehyde + H2O2.
