Protein

Monomeric sarcosine oxidase

Gene

soxA

Organism
Bacillus sp. (strain B-0618)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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

Catalytic activityi

Sarcosine + H2O + O2 = glycine + formaldehyde + H2O2.

Cofactori

FADNote: Binds 1 FAD per subunit.

Enzyme regulationi

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.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
