WebJan 2, 2024 · The results showed that the optimal temperature for ALP activity was 37 °C, and the optimal pH was 8.5. But ALP was stable at temperatures below 32 °C. The ALP activity remained at 80% when the pH was 8–9.5. The enzyme activity could be activated by Mg 2+, Ca 2+, and inhibited by Cu 2+, Zn 2+, and EDTA. WebAlkaline phosphatase (ALP) is a family of isoenzymes that catalyze the hydrolysis of a number of phosphate esters at an alkaline pH optimum. This glycoprotein requires zinc for activity. ALP are coded by four genes, 51 including one that codes for ALP isoenzymes from liver, bone, first-trimester placenta, and kidney.
