Sentence examples for has a ph optima from inspiring English sources
The lipase has a pH optima of 11.0 and active under broad temperature range of 25 100°C [ 11].
Boric acid, however, has a pH of 3.8 to 4.8.
To investigate whether A-SMase activity could facilitate formation of membrane protrusions and membrane vesiculation, microglia were exposed to exogenous recombinant SMase (r-SMase), which has an acid pH optima and displays little activity at neutral pH.
The partially purified r AciHBGase II–(His 6 protein appeared to be active under relatively acidic conditions with a pH optima of 3.5, and with > 80% activity at pH 3.5 5.0, as well as being more acid-stabile than neutral to alkali.
A metallocarboxypeptidase from S. cinnamoneus TH-2 (TH2-CP) has the pH optima of 7.0 and 8.0 in potassium phosphate buffer and Tris HCl buffer, respectively.
Interestingly, as with the Drosophila FDL (Léonard et al. 2006), the Apis FDL also has higher pH optima toward N-glycan substrates than toward pNP-β-GlcNAc/GalNAc; this was not observed for any of the Caenorhabditis enzymes described in this study (data not shown).
The notion of type was supported by the observation that different myosin heavy chain (MyHC) ATPases have different pH optima allowing histochemical procedures to display a checkerboard-like staining pattern with distinct black and white fibres observed in cross sections (Brooke & Kaiser, 1970).
Target mutation sites were selected by structural alignment between B. circulans xylanase and other xylanases having different pH optima.
The second generation, having higher pH optima (10 11) and greater temperature stability, is produced from alkalophilic strains including Bacillus clausii and B. halodurans.
Using fluorogenic dipeptidyl substrates, rhodesain and cruzain had acid pH optima, but unlike some mammalian cathepsins retained significant activity and stability up to pH 8.0, consistent with a possible extracellular function.
