Lysine at ph 5
WebAt pH=5.5, histidine-containing peptides had the same or even more potent activity as peptide LL-1 ( Fig. 1B ). Since the solution pHs in the range of pH=7.4 ~ 5.5 had no effects on cytotoxicity results from MTT assay [ 21 ], the pH sensitivity of histidine-containing peptides was not an artifact.

EcLdcC and EcCadA activities exhibited a similar tendency in whole-cell biotransformation of the crude l-lysine-free base solution. Although high alkaline pH conditions led to the gradual inactivation ...
WebActually what she doesn't tell you is that the pKa can be altered hugely depending on the actual local environment the chemical group is present in. Proteins are very good at altering the environment of different amino acids by folding into an ordered state. Histidine has a pKa around 6-7ish dependent on who you ask.
