Assertion: cysteine | /r/HasAspect | negative side chain
Facets:
value: potentially
type: MANNER
value: with 8.14
type: OTHER

text: Cysteine also has potentially negative side chain with pKa R = 8.14, so pI should be calculated as for Asp and Glu, even though the side chain is not significantly charged at physiological pH. For His, Lys, and Arg with positive side chains, pI = ½(pKa R + pKa 2 ).
