Abstract
The Munich Information Center for Protein Sequences (MIPS-GSF, Neuherberg, Germany) combines automatic processing of large amounts of sequences with manual annotation of selected model genomes. Due to the massive growth of the available data, the depth of annotation varies widely between independent databases. Also, the criteria for the transfer of information from known to orthologous sequences are diverse. To cope with the task of global in-depth genome annotation has become unfeasible. Therefore, our efforts are dedicated to three levels of annotation: (i) the curation of selected genomes, in particular from fungal and plant taxa (e.g. CYGD, MNCDB, MatDB), (ii) the comprehensive, consistent, automatic annotation employing exhaustive methods for the computation of sequence similarities and sequence-related attributes as well as the classification of individual sequences (SIMAP, PEDANT and FunCat) and (iii) the compilation of manually curated databases for protein interactions based on scrutinized information from the literature to serve as an accepted set of reliable annotated interaction data (MPACT, MPPI, CORUM). All databases and tools described as well as the detailed descriptions of our projects can be accessed through the MIPS web server (http://mips.gsf.de).

Abstract
The Munich Information Center for Protein Sequences (MIPS at the GSF), Neuherberg, Germany, provides resources related to genome information. Manually curated databases for several reference organisms are maintained. Several of these databases are described elsewhere in this and other recent NAR database issues. In a complementary effort, a comprehensive set of >400 genomes automatically annotated with the PEDANT system are maintained. The main goal of our current work on creating and maintaining genome databases is to extend gene centered information to information on interactions within a generic comprehensive framework. We have concentrated our efforts along three lines (i) the development of suitable comprehensive data structures and database technology, communication and query tools to include a wide range of different types of information enabling the representation of complex information such as functional modules or networks Genome Research Environment System, (ii) the development of databases covering computable information such as the basic evolutionary relations among all genes, namely SIMAP, the sequence similarity matrix and the CABiNet network analysis framework and (iii) the compilation and manual annotation of information related to interactions such as protein–protein interactions or other types of relations (e.g. MPCDB, MPPI, CYGD). All databases described and the detailed descriptions of our projects can be accessed through the MIPS WWW server ().

Abstract
The Comprehensive Yeast Genome Database (CYGD) compiles a comprehensive data resource for information on the cellular functions of the yeast Saccharomyces cerevisiae and related species, chosen as the best understood model organism for eukaryotes. The database serves as a common resource generated by a European consortium, going beyond the provision of sequence information and functional annotations on individual genes and proteins. In addition, it provides information on the physical and functional interactions among proteins as well as other genetic elements. These cellular networks include metabolic and regulatory pathways, signal transduction and transport processes as well as co-regulated gene clusters. As more yeast genomes are published, their annotation becomes greatly facilitated using S.cerevisiae as a reference. CYGD provides a way of exploring related genomes with the aid of the S.cerevisiae genome as a backbone and SIMAP, the Similarity Matrix of Proteins. The comprehensive resource is available under http://mips.gsf.de/genre/proj/yeast/.

Abstract
The Munich Information Center for Protein Sequences (MIPS-GSF), Neuherberg, Germany, provides protein sequence-related information based on whole-genome analysis. The main focus of the work is directed toward the systematic organization of sequence-related attributes as gathered by a variety of algorithms, primary information from experimental data together with information compiled from the scientific literature. MIPS maintains automatically generated and manually annotated genome-specific databases, develops systematic classification schemes for the functional annotation of protein sequences and provides tools for the comprehensive analysis of protein sequences. This report updates the information on the yeast genome (CYGD), the Neurospora crassa genome (MNCDB), the database of complete cDNAs (German Human Genome Project, NGFN), the database of mammalian protein-protein interactions (MPPI), the database of FASTA homologies (SIMAP), and the interface for the fast retrieval of protein-associated information (QUIPOS). The Arabidopsis thaliana database, the rice database, the plant EST databases (MATDB, MOsDB, SPUTNIK), as well as the databases for the comprehensive set of genomes (PEDANT genomes) are described elsewhere in the 2003 and 2004 NAR database issues, respectively. All databases described, and the detailed descriptions of our projects can be accessed through the MIPS web server (http://mips.gsf.de).

Abstract
The aim of the MitoP2 database (http://ihg.gsf.de/mitop2) is to provide a comprehensive list of mitochondrial proteins of yeast and man. Based on the current literature we created an annotated reference set of yeast and human proteins. In addition, data sets relevant to the study of the mitochondrial proteome are integrated and accessible via search tools and links. They include computational predictions of signalling sequences, and summarize results from proteome mapping, mutant screening, expression profiling, protein-protein interaction and cellular sublocalization studies. For each individual approach, specificity and sensitivity for allocating mitochondrial proteins was calculated. By providing the evidence for mitochondrial candidate proteins the MitoP2 database lends itself to the genetic characterization of human mitochondriopathies.

Abstract
The SWI-SNF and SAGA complexes possess ATP-dependent nucleosome remodelling activity and histone acetyltransferase (HAT) activity, respectively. Mutations that eliminate the ATPase activity of the SWI-SNF complex, or the HAT activity of SAGA, abolish proper chromatin remodelling at the PHO8 promoter in vivo. These effects are mechanistically distinct, since the absence of SWI-SNF freezes chromatin in the repressed state, while the absence of Gcn5 permits a localized perturbation of chromatin structure immediately adjacent to the upstream transactivator binding site. However, this remodelling is not propagated to the proximal promoter, and no activation is observed under all conditions. Furthermore, Pho4 is bound to the PHO8 promoter in the absence of Snf2 or Gcn5, confirming a role for SWI-SNF and SAGA in chromatin remodelling independent of activator binding. These data provide new insights into the roles of the SWI-SNF and SAGA complexes in chromatin remodelling in vivo.

Abstract
The activation of the PHO5 gene in Saccharomyces cerevisiae in response to phosphate starvation critically depends on two transcriptional activators, the basic helix-loop-helix protein Pho4 and the homeodomain protein Pho2. Pho4 acts through two essential binding sites corresponding to the regulatory elements UASp1 and UASp2. Mutation of either of them results in a 10-fold decrease in promoter activity, and mutation of both sites renders the promoter totally uninducible. The role of Pho4 appears relatively straightforward, but the mechanism of action of Pho2 had remained elusive. By in vitro footprinting, we have recently mapped multiple Pho2 binding sites adjacent to the Pho4 sites, and by mutating them individually or in combination, we now show that each of them contributes to PHO5 promoter activity. Their function is not only to recruit Pho2 to the promoter but to allow cooperative binding of Pho4 together with Pho2. Cooperativity requires DNA binding of Pho2 to its target sites and Pho2-Pho4 interactions. A Pho4 derivative lacking the Pho2 interaction domain is unable to activate the promoter, but testing of UASp1 and UASp2 individually in a minimal CYC1 promoter reveals a striking difference between the two UAS elements. UASp1 is fully inactive, presumably because the Pho4 derivative is not recruited to its binding site. In contrast, UASp2 activates strongly in a Pho2-independent manner. From in vivo footprinting experiments and activity measurements with a promoter variant containing two UASp2 elements, we conclude that at UASp2, Pho2 is mainly required for the ability of Pho4 to transactivate.

Abstract
Two transcription factors, the bHLH protein Pho4 and the homeodomain protein Pho2, are required for transcriptional activation of the PHO5 promoter in Saccharomyces cerevisiae. There are two essential Pho4 binding sites, corresponding to the regulatory elements UASp1 and UASp2 at the PHO5 promoter, but only a single, dispensable Pho2 binding site had previously been identified. We have reinvestigated binding of Pho2 to the PHO5 promoter using purified recombinant protein and have found multiple Pho2 binding sites of different affinities along the promoter. One of the high affinity Pho2 sites largely overlaps the Pho4 binding site at UASp1. Cooperative DNA binding of the two proteins to their overlapping sites, resulting in a high-affinity ternary complex, was demonstrated. Pho2 and Pho4 also bind DNA cooperatively at UASp2 where two Pho2 sites flank the Pho4 site. Finally, Pho2 facilitates binding of Pho4 to a third, cryptic Pho4 binding site which binds Pho4 with lower affinity than UASp1 or UASp2. These results suggest that cooperative DNA binding with Pho4 is integral to the mechanism by which Pho2 regulates transcription of the PHO5 gene.
