Protein

Cytosolic non-specific dipeptidase

Gene

Cndp2

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Hydrolyzes a variety of dipeptides including L-carnosine but has a strong preference for Cys-Gly. Catalyzes the production of N-lactoyl-amino acids from lactate and amino acids by reverse proteolysis.By similarity

Catalytic activityi

Hydrolysis of dipeptides, preferentially hydrophobic dipeptides including prolyl amino acids.1 Publication

Cofactori

Mn2+2 PublicationsNote: Binds 2 manganese ions per subunit.2 Publications

Activity regulationi

Inhibited by bestatin.1 Publication
