One-step characterization of a eukaryotic cell pro-teome is difficult if not impossible to achieve. There is a growing trend in eukaryotes proteomics toward characterization of subcellular structures. The reason for this shift from global proteomics to subcellular proteomics is the complexity of eukaryotic cells and subcellular organelles. Therefore the proteomic analysis of subcellular organelles will be an important aspect of toxicoproteomics. 

Recent proteomic analysis indicated that the cilia of mammalian photoreceptor cells are significantly more complex than other eukaryotic cilium (Liu et al. 2006). Over 1200 different polypeptides have been identified by the quantitative analysis of the proteome of photoreceptor outer segment compared with the proteome of the axoneme/ciliary fraction of mouse photoreceptor cells. This data set contains all previously identified protein components of the photoreceptor cilium (e.g. Schmitt and Wolfrum 2001). An understanding how the identified proteins function in their native environment of the diverse compartments of the photoreceptor cilia will require increased knowledge of their molecular interaction and networking. Insights into the organization and composition of diverse protein complexes may also provide novel information on how functional modules of the cell, recently proposed by Hofmann et al. 2006, are connected.

The analysis of adenylylation requires preparatively adenylylated proteins in order to determine the site of the PTM, to determine the structure of the modified proteins, and to establish the functional consequences for Rabl-activity. Also, the systematic investigation of adenylylation in live cells and their distribution among different prokaryotic and eukaryotic proteomes requires specific tools... 

Before we describe the chemistry of the compartments involved, note that like prokaryotes, a number of oxidative enzymes are found in the cytoplasm but they do not release damaging chemicals (see Section 6.10). We also observed that such kinds of kinetic compartments are not enclosed by physical limitations such as membranes. We have also mentioned that increased size itself makes for kinetic compartments if diffusion is restricted. In this section, we see many additional advantages of eukaryotes from those given in Section 7.4. How deceptive it can be to use just the DNA, the all-embracing proteome, metabolome or metallome in discussing evolution without the recognition of the thermodynamic importance of compartments and their concentrations These data could be useful both here and in simpler studies of single-compartment bacteria even in the analysis of species but not much information is available.

The relatively new field termed proteomics deals with the assignment of molecular and cellular functions to the tens of thousands of protein products encoded by prokaryotic and eukaryotic genomes. In addition, it seeks to develop and apply new methods for the global analysis of protein expression and protein function. These methods must fulfill distinct requirements ranging from the analysis of many proteins in parallel and in samples of high complexity up to the characterization of proteins in a dynamic cellular environment, in which these biomolecules are subject to a myriad of post-translational modifications and actions ofvarious activators and inhibitors [250,251].
