Toxoplasma gondii NTPDase1 C258S/C268S in complex with Mg and AMPNP
Template:ABSTRACT PUBMED 24115522
Function
[NTP2_TOXGO] May perform an important processing step in the conversion of high energy nucleotides prior to uptake by the parasite. NTPAse-II has a specific activity 4.5-fold lower than NTPAse-I in hydrolysis of ATP. The primary difference between these isozymes lies in their ability to hydrolyze nucleoside triphosphate versus diphosphate substrates. While NTPAse-II hydrolyzes ATP to ADP and ADP to AMP at almost the same rate, NTPAse-I hydrolyzes ADP to AMP at a much slower rate (0.7% of the rate for ATP).
About this Structure
4kh5 is a 2 chain structure with sequence from Toxgo. Full crystallographic information is available from OCA.
