UniProtKB - O75354 (ENTP6_HUMAN)

Protein

Ectonucleoside triphosphate diphosphohydrolase 6

Gene

ENTPD6

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Might support glycosylation reactions in the Golgi apparatus and, when released from cells, might catalyze the hydrolysis of extracellular nucleotides. Hydrolyzes preferentially nucleoside 5'-diphosphates, nucleoside 5'-triphosphates are hydrolyzed only to a minor extent, there is no hydrolysis of nucleoside 5'-monophosphates. The order of activity with different substrates is GDP > IDP >> UDP = CDP >> ADP (By similarity).By similarity

Catalytic activityi

A nucleoside diphosphate + H2O = a nucleoside phosphate + phosphate.

Cofactori

Ca2+By similarity, Mg2+By similarity
