1 OBJECTIVE: Alkaline phosphatase (ALP), an enzyme with pyrophosphatase (PPiase) activity can dissolve calcium pyrophosphate dihydrate (CPPD) crystals. Calcium Pyrophosphate FKBP prolyl isomerase 1B Homo sapiens
2 OBJECTIVE: Alkaline phosphatase (ALP), an enzyme with pyrophosphatase (PPiase) activity can dissolve calcium pyrophosphate dihydrate (CPPD) crystals. Calcium Pyrophosphate FKBP prolyl isomerase 1B Homo sapiens
3 We studied the effects of enzyme inhibitors such as bisphosphonates, orthovanadate, calcium, cadmium, and ascorbic acid on PPiase activity of ALP as well as on phosphate ester hydrolysis (Pase) activity and compared these effects to those on CPPD crystal dissolution. Diphosphonates FKBP prolyl isomerase 1B Homo sapiens
4 We studied the effects of enzyme inhibitors such as bisphosphonates, orthovanadate, calcium, cadmium, and ascorbic acid on PPiase activity of ALP as well as on phosphate ester hydrolysis (Pase) activity and compared these effects to those on CPPD crystal dissolution. Calcium FKBP prolyl isomerase 1B Homo sapiens
5 We studied the effects of enzyme inhibitors such as bisphosphonates, orthovanadate, calcium, cadmium, and ascorbic acid on PPiase activity of ALP as well as on phosphate ester hydrolysis (Pase) activity and compared these effects to those on CPPD crystal dissolution. Cadmium FKBP prolyl isomerase 1B Homo sapiens
6 We studied the effects of enzyme inhibitors such as bisphosphonates, orthovanadate, calcium, cadmium, and ascorbic acid on PPiase activity of ALP as well as on phosphate ester hydrolysis (Pase) activity and compared these effects to those on CPPD crystal dissolution. Ascorbic Acid FKBP prolyl isomerase 1B Homo sapiens
7 Calcium inhibited ALP PPiase activity, but not ALP Pase activity. Calcium FKBP prolyl isomerase 1B Homo sapiens
8 Orthovanadate and cadmium inhibited ALP PPiase activity more than ALP Pase at the same concentrations. Vanadates FKBP prolyl isomerase 1B Homo sapiens
9 Orthovanadate and cadmium inhibited ALP PPiase activity more than ALP Pase at the same concentrations. Cadmium FKBP prolyl isomerase 1B Homo sapiens
10 The inhibition rates of ALP PPiase at the same concentrations were orthovanadate > cadmium > calcium. Vanadates FKBP prolyl isomerase 1B Homo sapiens
11 The inhibition rates of ALP PPiase at the same concentrations were orthovanadate > cadmium > calcium. Cadmium FKBP prolyl isomerase 1B Homo sapiens
12 The inhibition rates of ALP PPiase at the same concentrations were orthovanadate > cadmium > calcium. Calcium FKBP prolyl isomerase 1B Homo sapiens
13 Although ALP Pase activity was not inhibited, at high concentrations, ascorbic acid slightly inhibited ALP PPiase activity. Ascorbic Acid FKBP prolyl isomerase 1B Homo sapiens
14 The strong inhibitory effects of bisphosphonates on ALP CPPD crystal dissolution compared to those on ALP PPiase activity suggest that bisphosphonates inhibit crystal dissolution by their affinity for the CPPD crystal surface. Diphosphonates FKBP prolyl isomerase 1B Homo sapiens
