Carnosine synthase 1; Catalyzes the synthesis of carnosine and homocarnosine. Carnosine is synthesized more efficiently than homocarnosine (950 aa)

Carnosine dipeptidase 1 (metallopeptidase M20 family) (507 aa)

CNDP dipeptidase 2 (metallopeptidase M20 family); Hydrolyzes a variety of dipeptides including L-carnosine but has a strong preference for Cys-Gly (PubMed-19346245). Acts as a functional tumor suppressor in gastric cancer via activation of the mitogen-activated protein kinase (MAPK) pathway. An elevated level of CNDP2 activates the p38 and JNK MAPK pathways to induce cell apoptosis, and a lower level of CNDP2 activates the ERK MAPK pathway to promote cell proliferation (PubMed-24395568). Isoform 2 may play a role as tumor suppressor in hepatocellular carcinoma (HCC) cells (PubMed-17121 [...] (475 aa)

Histidine decarboxylase; Catalyzes the biosynthesis of histamine from histidine (662 aa)

Amidohydrolase domain containing 1 (426 aa)

Dopa decarboxylase (aromatic L-amino acid decarboxylase); Catalyzes the decarboxylation of L-3,4- dihydroxyphenylalanine (DOPA) to dopamine, L-5-hydroxytryptophan to serotonin and L-tryptophan to tryptamine (480 aa)

Formiminotransferase cyclodeaminase; Folate-dependent enzyme, that displays both transferase and deaminase activity. Serves to channel one-carbon units from formiminoglutamate to the folate pool (541 aa)

Carbohydrate (chondroitin 6) sulfotransferase 3; Sulfotransferase that utilizes 3’-phospho-5’-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the transfer of sulfate to position 6 of the N-acetylgalactosamine (GalNAc) residue of chondroitin. Chondroitin sulfate constitutes the predominant proteoglycan present in cartilage and is distributed on the surfaces of many cells and extracellular matrices. Can also sulfate Gal residues of keratan sulfate, another glycosaminoglycan, and the Gal residues in sialyl N- acetyllactosamine (sialyl LacNAc) oligosaccharides. May play a role in th [...] (479 aa)
