WebOur 7-hydroxy-9H-(1,3-dichloro-9,9-dimethylacridin-2-one (DDAO phosphate, D6487) phosphatase substrate yields a hydrolysis product that is efficiently excited by the 633 nm spectral line of the He-Ne laser to produce bright red fluorescence with absorption/emission maxima of ~646/659 nm (Figure 10.3.1). WebAs described in Section 8.23.3.5, phosphatases are generally dinuclear metalloenzymes with Zn 2 +, Fe 3 +, Mn 2 +, Mg 2 +, etc. Typically, alkaline phosphatases (AP) are dimetallic Zn 2 + hydrolases. As shown in Scheme 10, Ser102 of AP is apparently activated by Zn 2 + to attack at phosphate substrates polarized by another Zn 2 + ion. gryphon capital income trust https://connersmachinery.com
