Structural highlights 3typ is a 2 chain structure with sequence from Nitrosomonas europaea. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 1.9Å Ligands: , Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function 3PASE_NITEU Involved in the hydrolysis of the beta-gamma-phosphoanhydride linkage of triphosphate-containing substrates (inorganic or nucleoside-linked). Catalyzes the hydrolysis of inorganic triphosphate (PPPi). The enzyme has a strong preference for linear PPPi compared with cyclic PPPi (cyclic trimetaphosphate) and to the linear P4. The longer chains polyphosphate are not hydrolyzed. It has only a slight thiamine triphosphatase (ThTPase) activity. Nucleoside triphosphatase activity is negligible in the presence of magnesium, but a small activity is observed in the presence of manganese, in particular with GTP.
