Fragmentation of Peptide Disulfides under Conditions of Negative Ion Mass Spectrometry: Studies of Oxidized Glutathione and Contryphan (2008)

Thakur, Suman S, Balaram, Padmanabhan

The fragmentation of positive and negative ions of peptide disulfides under mass spectrometric conditions yields distinctly different product ion distributions. A negative ion upon collision induced...

De Novo Sequencing and Disulfide Mapping of a Bromotryptophan-Containing Conotoxin by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (2006)

Nair, Sudarslal Sadasivan, Nilsson, Carol L, Emmett, Mark R, Schaub, Tanner M, Gowd, Konkallu Hanumae, Thakur, Suman S, ...

T-1-family conotoxins belong to the T-superfamily and are composed of 10-17 amino acids. They share a common cysteine framework and disulfide connectivity and exhibit unusual posttranslational...

Detoxification of Chemical Warfare Agents by the Plant Cholinergic System (1998)

Thakur, Suman S., Garcia, Gregory E., Leader, Haim N., Moorad-Doctor, Deborah, Gupta, Rajendra, Gordon, Richard K., ...

Plants have cholinesterases (pChEs), anti-ChEs, and activators of ChEs. We have isolated pChE from mung bean sprout. We investigated 300 plants and found that 75% of them contained anti- ChE that...
