pI (or isoelectric point) is the pH at which a molecule has no net charge. Mathematically, it is defined as the mean of the pKa values for a molecule. Simple! So, the pI of a protein is determined by the pKa of every amino constituent amino acid. ...
Both pH and pKa have formulas that can help show how acidic a substance is. pH has its own range, as does pKa. They have a relationship with one another that also can show how acidic something is. Answer and Explanation:1 The pH scale is a range from 0-14. Generally speaking 0-2 ...

PDB formats were first prepared by PDB2PQR web server converted to PQR format using CHARMM force field with PROPKA set at pH = 7.057. Thereafter, we carried out the APBS analysis via Linearized Poisson-Boltzmann Equation in VMD software with settings parameters: solvent dielectric constant ...
(YxxL) appears to be another recognition motif of AP2, although it is not as crucial as Motif D. Motifs A and C are two phosphorylated motifs [51]. They have a similar sequence pattern RXXpS, which matches the recognition sites of some AGC kinases such as PKA, PKB and PKC [52]. ...
The greater the magnitude of the acid dissociation constant, the stronger the acid. In addition, we find that we can express the strength of an acid in terms of its pKa. The pKa is the negative logarithm of the acid dissociation constant....

In steroidogenic cells, apoE expression and cholesterol homeostasis are affected by agents that alter cAMP-dependent protein kinase A (PKA) and protein kinase C (PKC) activities (51, 52). As the cl.1 vim+ and IF-free cl.2 cells do not appear to substantially differ in apoE mRNA levels,...
The level of inactive cells will depend on the conditions of the biomass production process, such as the growth phase at harvesting, medium composition or the pH profile throughout fermentation. Thus, because postbiotics will be derived from both active and inactive cells, CFU counts prior to ...
