Carbonyl-Amine Reactions in Protein Chemistry

1975
Publisher Summary Reaction of a carbonyl group with an amino group is the key reaction in many enzymic and other biological processes, such as vision. This chapter discusses and attempts to organize and correlate the different types of carbonyl–amine reactions found in proteins with their organic chemistry.

Determination of Protein Carbonyl Groups by Immunoblotting

Analytical Biochemistry, 1999
Free radical-mediated oxidation of proteins results in the formation of carbonyl groups in quantities that reflect the intensity of the oxidative stress. We have developed an immunochemical technique for the quantification of carbonyl groups in protein samples prepared from small tissue samples and cell cultures.

Protein carbonylation: Proteomics, specificity and relevance to aging

Mass Spectrometry Reviews, 2013
AbstractDetection and quantification of protein carbonyls present in biological samples has become a popular, albeit indirect, method to determine the existence of oxidative stress. Moreover, the rise of proteomics has allowed the identification of the specific proteins targeted by protein carbonylation.

Interresidue carbonyl–carbonyl polarization transfer experiments in uniformly 13C,15N-labeled peptides and proteins

Journal of Magnetic Resonance, 2010
In this work, we demonstrate that Homonuclear Rotary Resonance Recoupling (HORROR) can be used to reintroduce carbonyl-carbonyl interresidue dipolar interactions and to achieve efficient polarization transfer between carbonyl atoms in uniformly (13)C,(15)N-labeled peptides and proteins. We show that the HORROR condition is anisotropically broadened and

Reversible Protein Carbonylation In-Vivo Biosensor

Optical Sensors and Sensing Congress (ES, FTS, HISE, Sensors), 2019
We show preliminary results of an optical fiber based reversible in-vivo biosensor for understanding redox balance within living systems. The biosensor measured protein carbonyls (oxygen metabolism marker) in pig-skin, live mouse, and wheat plant.

Protein carbonyls in meat systems: A review

Meat Science, 2011
Protein oxidation (P-OX) is an innovative topic of increasing interest among meat researchers. Carbonylation is generally recognized as one of the most remarkable chemical modifications in oxidized proteins. In fact, the quantification of protein carbonyls by the dinitrophenylhydrazine (DNPH) method is the most common procedure for assessing P-OX in ...
