Protein carbonyl formation: Metal-Catalyzed Oxidation

Physiological consequences can be inferred due to the specificity

  • f protein functions

Products (damage) are relatively stable Sensitive assays are available

Why using proteins as markers of oxidative stress?

Carbonylation: Irreversible. Associated with protein dysfunction

Oxidative damage to proteins and disease

  • some examples-

 Neurodegenerative diseases

  • Alzheimer
  • Parkinson
  • Sporadic amyotrophic lateral sclerosis
  • Friedreich ataxia

 Muscular dystrophy  Iron disorders  Aging  Progeria  Atherosclerosis  Ischemia-reperfusion injury  Acute pancreatitis  Chronic ethanol ingestion

Oxidative damage to proteins: importance beyond the original cause of the disease: worsening cell functions

Sequences Prone to Carbonylation

Most of the sites—approximately 75% — were grouped in the regions containing sequences rich in the amino acids Arg (R), Lys (K), Pro (P), and Thr (T) (i) the impact in these sites with RKPT-rich sequences was four times greater than in other regions Among the 21 classes of assigned functions, proteins involved in translation and ribosomal structure showed the highest percentage of carbonylatable sites when compared to the mean value of the whole E. coli proteome. This also applies to proteins involved in energy production or in nucleotide transport. Maisonneuve E et al. 2009. PLoS One.4(10) RULES EXPLAINING THE SPECIFICITY OF PROTEIN DAMAGE?
