O-(S-L-prolylpantetheine-4'-phosphoryl)serine zwitterionic residue
o-(s-l-prolylpantetheine-4'-phosphoryl)serine zwitterionic residue
An <em>O</em>-[<em>S</em>-(<small>L</small>-α-aminoacyl)pantetheine-4'-phosphoryl]serine zwitterionic residue obtained by transfer of a proton from the phosphate to the amino group of <em>O</em>-(<em>S</em>-<small>L</small>-prolylpantetheine-4'-phosphoryl)serine residue; major microspecies at pH 7.3.
