All residues were protonated based on neutral pH after the assignment of bond orders using the Dock prep tool in Chimera.
To obtain detailed information on the assignment of disulfide bonds in a protein, a 100%% reduction of all bonds is not always desirable.
The electrochemical reduction shows great potential in proteomics applications particularly for the assignment of disulfide bonds in proteins and the cleavage of TCEP-resistant disulfide bonds is important for hydrogen deuterium (H D) exchange.
This is particularly useful for assignment of disulfide bonds in proteins, when controlled partial reduction is desired, rather than 100%reductionon.
The use of a chemical reductant leads usually to 100%% reduction, and the information about the assignment of disulfide bonds is lost.
Many such issues complicate the counting and assignment of hydrogen bond acceptors and hydrogen bond donor groups.
An important part of atom typing is aromaticity detection and assignment of Kekulé bond orders (kekulization).
The objection respecting the assignment of a bond to a citizen of another State, has been fully answered.
The ligand preparation programs, like MarvinSketch (Marvin 6.1.6, 2014, http://www.chemaxon.com) or LigPrep (Schrödinger Release 2016-4: LigPrep, Schrödinger, LLC, New York, NY, 2016), show that N5 and N6 have the same pKa, and depending on the prior assignment of the bonding order, the protonation is made on either one or the other nitrogen.
The FAMEs were further derivatized with DMOX to enable diagnostic assignment of double bond positions in FA based on their fragmentation pattern upon mass spectrometric analysis.
The edges are labeled with modification operations depending on the related bond or interaction (for the assignment procedure of bond modifications see [6]).
