Biology Selenocysteine has both a lower pKa (5.47) and a lower reduction potential than cysteine.
The mechanism of activation is similar to that of PKA: the GEF domain is usually masked by the N-terminal region containing the cAMP binding domain.
The level of cytosolic cAMP may then determine the activity of various ion channels as well as members of the ser/thr-specific protein kinase A (PKA) family.
For amino acids with charged side-chains, the pKa of the side-chain is involved.
The individual amino acids all have slightly different pKa values, so have different isoelectric points.
Years later, the first example of a kinase cascade was identified, whereby Protein Kinase A (PKA) phosphorylates Phosphorylase Kinase.
