A1 - Jakubowski, Norbert T1 - Cytochromes - fascinating molecular machines N2 - A huge number of functions and reactions can be performed by proteins merely based on their amino acids and their spatial arrangement which results in a specific geometric and electronic environment. The diversity and efficiency of functions, however, can be increased by protein-bound cofactors which fulfil their task in close interaction with the surrounding amino acid side chains. Among these cofactors, metals play an important role. They can be bound to proteins directly via specific amino acids such as cysteine and histidine, for example in zinc finger proteins or in iron sulfur cluster proteins. Another possibility is their integration into the 3D-structure of a protein via a prosthetic group. Porphyrine or porphyrine-like molecules with copper or iron as central bound metal ions constitute important structures in this respect.

T1 - Iodination of proteins, proteomes and antibodies with potassium triodide for LA-ICP-MS based proteomic analyses N2 - A fast and mild method for iodine labelling of proteins is presented which is specifically designed and optimized for laser ablation (LA-)ICP-MS based proteomics. Single proteins (lysozyme, bovine serum albumin, cytochrome c and β-casein), whole proteomes (microsomal proteome of rats) and antibodies (anti-bovine casein, anti-bovine serum albumin) can be efficiently iodinated by means of potassium triiodide with minimal losses of antigen properties and antibody binding to iodinated proteins. A comparison with iodination by use of IODO-Beads is presented and it is shown that triiodide labelling is a fast, cheap and less laborious alternative without compromising the analytical figures of merit.

A1 - Jakubowski, Norbert T1 - Combined application of a laser ablation-ICP-MS assay for screening and ESI-FTICR-MS for identification of a Cd-binding protein in Spinacia oleracea L. after exposure to Cd N2 - We have studied the binding of the toxic element Cd to plant proteins and have used for this purpose spinach (Spinacia oleracea L.) plants treated with 50 µM Cd(II) as a model system. Laser ablation ICP-MS has been applied for the screening of Cd-binding proteins after separation by native anodal polyacrylamide gel electrophoresis (AN-PAGE) and electroblotting onto membranes. The main Cd-carrying protein band was isolated and investigated by nano-electrospray ionization–Fourier transform ion cyclotron resonance (FTICR) mass spectrometry after tryptic digestion. By this procedure, the main Cd-binding protein was identified as ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). The latter enzyme has been discussed in the literature to be affected in its activity by oxidative stress induced by Cd. However, in this paper it is demonstrated for the first time that RuBisCO directly binds Cd and thus may be directly altered by this toxic element. A commercially available protein standard was used to verify direct binding of Cd(II) to the protein, even without metabolisation. The resulting metal–protein complex was shown to be stable enough to survive AN-PAGE separation and electroblotting. By the use of size exclusion chromatography coupled with ICP-MS it was demonstrated that the RuBisCO protein standard shows similar metal binding properties to Cd. Furthermore, essential elements such as Mn(II), Fe(II) and Cu(II), which are known to possibly replace the RuBisCO activator Mg(II), were investigated in addition to Zn(II). Again, similar binding properties in comparison to the plant protein were observed.

T1 - LA-ICP-MS and nHPLC-ESI-LTQ-FT-MS/MS for the analysis of cisplatin-protein complexes separated by two dimensional gle elctrophoresis in biological samples N2 - A method for the analysis of Pt–protein complexes in biological samples, previously subjected to cisplatin treatment, has been developed. Proteins were separated by gel electrophoresis, and those bound to Pt were detected with high sensitivity by LA-ICP-(SF)-MS. Pt-containing spots were in-gel digested with trypsin, and the peptides produced identified using nHPLC-ESI-LTQ-FT-MS/MS. The influence of protein separation conditions, staining and gel processing prior to laser ablation on Pt–protein bonds preservation have been evaluated using standard proteins incubated with cisplatin. 2-DE separation under non-reducing conditions followed by either Coomassie blue brilliant or silver staining is appropriate for Pt–protein complexes, achieving a good separating resolution of the proteins in biological samples. Direct LA-ICP-MS analysis of glycerol-treated dried gels for Pt–protein monitoring resulted in better sensitivity, more reliable relative Pt signals and a simpler and less time-consuming approach compared to the analysis of blotted membranes. Ablation of gels allowed tackling protein identification of Pt-spots in the remaining non-ablated material in the gel, making it unnecessary to run several gels in parallel for separate Pt detection and protein identification. By using this approach, Pt coordinated to proteins, such as α-2-macroglobulin, transferrin, albumin or hemoglobin, was detected in the serum from a rat treated in vivo with cisplatin after nrSDS-PAGE separation. Furthermore, the first complete LA-ICP-MS metalloprotein contour map in a 2-DE gel has been produced, in this case for the detection of Pt–protein complexes in renal proximal tubule epithelial cells (RPTECs) incubated with cisplatin. Several proteins were identified in those spots containing Pt, which may have a connection with the drug-induced nephrotoxicity mainly affecting this cell type in the kidney.

T1 - A multi-parametric microarray for protein profiling: simultaneous analysis of 8 different cytochromes via differentially element tagged antibodies and laser ablation ICP-MS N2 - The paper presents a new multi-parametric protein microarray embracing the multi-analyte capabilities of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The combination of high throughput reverse phase protein microarrays with element tagged antibodies and LA-ICP-MS makes it possible to detect and quantify many proteins or biomarkers in multiple samples simultaneously. A proof of concept experiment is performed for the analysis of cytochromes particularly of cytochrome P450 enzymes, which play an important role in the metabolism of xenobiotics such as toxicants and drugs. With the aid of the LA-ICP-MS based multi-parametric reverse phase protein microarray it was possible to analyse 8 cytochromes in 14 different proteomes in one run. The methodology shows excellent detection limits in the lower amol range and a very good linearity of R² ≥ 0.9996 which is a prerequisite for the development of further quantification strategies.
