General annotation (Comments)

Function

Catalyzes the oxidative demethylation of sarcosine. Can also oxidize other secondary amino acids such as N-methyl-L-alanine. HAMAP-Rule MF_00516

Catalytic activity

Sarcosine + H2O + O2 = glycine + formaldehyde + H2O2. HAMAP-Rule MF_00516

Cofactor

Binds 1 FAD per subunit.

Enzyme regulation

Pyrrole-2-carboxylate is a competitive inhibitor. N-(cyclopropyl)glycine (CPG) is a mechanism-based inhibitor and inactivates the enzyme by covalently modifying the flavin. HAMAP-Rule MF_00516

Subunit structure

Monomer.

Subcellular location

Cytoplasm HAMAP-Rule MF_00516.

Sequence similarities

Belongs to the MSOX/MTOX family. MSOX subfamily.

Mass spectrometry

Molecular mass is 43839 Da from positions 1 - 390. Determined by ESI. Ref.3
