2. Protein pKa calculations - Wikipedia

   en.wikipedia.org/wiki/Protein_pKa_calculations

   In computational biology, protein pK a calculations are used to estimate the pK a values of amino acids as they exist within proteins.These calculations complement the pK a values reported for amino acids in their free state, and are used frequently within the fields of molecular modeling, structural bioinformatics, and computational biology.

3. Lysine - Wikipedia

   en.wikipedia.org/wiki/Lysine

   Lysine ball and stick model spinning. Lysine (symbol Lys or K) [2] is an α-amino acid that is a precursor to many proteins.Lysine contains an α-amino group (which is in the protonated −NH + 3 form when the lysine is dissolved in water at physiological pH), an α-carboxylic acid group (which is in the deprotonated −COO − form when the lysine is dissolved in water at physiological pH ...

4. Protein kinase A - Wikipedia

   en.wikipedia.org/wiki/Protein_kinase_A

   In cell biology, protein kinase A (PKA) is a family of serine-threonine kinase [1] whose activity is dependent on cellular levels of cyclic AMP (cAMP). PKA is also known as cAMP-dependent protein kinase (EC 2.7.11.11). PKA has several functions in the cell, including regulation of glycogen, sugar, and lipid metabolism.

6. Proteinogenic amino acid - Wikipedia

   en.wikipedia.org/wiki/Proteinogenic_amino_acid

   N.D.: The pKa value of Pyrrolysine has not been reported. Note: The pKa value of an amino-acid residue in a small peptide is typically slightly different when it is inside a protein. Protein pKa calculations are sometimes used to calculate the change in the pKa value of an amino-acid residue in this situation.

9. Histone acetylation and deacetylation - Wikipedia

   en.wikipedia.org/wiki/Histone_acetylation_and_de...

   Lysine is an amino acid with a positive charge when unmodified. Lysines on the amino terminal tails of histones have a tendency to weaken the chromatin's overall structure. Addition of an acetyl group, which carries a negative charge, effectively removes the positive charge and hence, reduces the interaction between the histone tail and the ...
