MDS Proteomics Unveils PepSea Technology, Enabling Targeted, High-Speed Protein Identification; Technology Makes Mining Novel Genes and Expressed Proteins Easier.Business Editors/Health & Medical Writers TORONTO--(BW HealthWire)--July 30, 2001 MDS MDS, n See temporomandibular pain-dysfunction syndrome. MDS 1 Maternal deprivation syndrome, see there 2 Myelodysplastic syndrome, see there Proteomics, a leading proteomics-based drug discovery company, today announced the addition of its PepSea(TM) technology, an advanced tool for protein identification, to its bioinformatics technology platform. PepSea now provides researchers with the tools to identify expressed proteins directly in the human genome The human genome is the genome of Homo sapiens, which is composed of 24 distinct pairs of chromosomes (22 autosomal + X + Y) with a total of approximately 3 billion DNA base pairs containing an estimated 20,000–25,000 genes. using mass spectrometric data. By implementing the technology on the company's high-speed supercomputing clusters, MDS Proteomics will have the ability to identify high-quality drug targets faster, thereby speeding the development of new medicines. Unraveling the mystery of protein activity is one of the largest challenges in scientific research and a key driver in the development of tools that enable the quick identification of high quality targets. Current proteomics technologies can only identify already known proteins or proteins predicted from genomic data. PepSea goes one step beyond, enabling the identification of unknown proteins with no prediction necessary. PepSea also can, in seconds, determine the location and identity of human genes that encode the proteins. Because of the error tolerance inherent in the PepSea algorithm, proteins can even be identified regardless of intervening sequences ("junk DNA junk DNA n. DNA that does not code for proteins or their regulation but is thought to be involved in the evolution of new genes and in gene repair, and constitutes approximately 95 percent of the human genome. " and introns), which make up the majority of human DNA DNA: see nucleic acid. DNA or deoxyribonucleic acid One of two types of nucleic acid (the other is RNA); a complex organic compound found in all living cells and many viruses. It is the chemical substance of genes. . This scientific breakthrough was recently announced in the journal Proteomics by Dr. Matthias Mann and his academic group at the University of Southern Denmark As a national institution the University of Southern Denmark (SDU) comprises five faculties – Humanities, Science, Engineering, Social Sciences and Health Sciences totaling 32 departments, 11 research centers and a university library. , Odense, together with researchers at MDS Proteomics in Odense, Denmark. "By allowing protein identification directly in raw human genome sequence, PepSea enables us to determine the identity and location of any human gene given an absolute minimum amount of protein," said Dr. Mann, chief proteomics officer of MDS Proteomics. Using just a fraction of the available power of its IBM (International Business Machines Corporation, Armonk, NY, www.ibm.com) The world's largest computer company. IBM's product lines include the S/390 mainframes (zSeries), AS/400 midrange business systems (iSeries), RS/6000 workstations and servers (pSeries), Intel-based servers (xSeries) multinode supercomputing cluster used for mining genomic sequence databases, MDS Proteomics is able to search the entire human genome in less than 5 seconds, fundamentally changing the rules of mass spectrometry mass spectrometry or mass spectroscopy Analytic technique by which chemical substances are identified by sorting gaseous ions by mass using electric and magnetic fields. . This is the first time this capability has been demonstrated. Based on the established application "PeptideSearch" developed by Mann, PepSea provides searches that are faster, error tolerant and of superior specificity.

"We expect this combination of technologies and expertise to broaden the scientific base from which, we and our pharmaceutical partners, will ultimately develop new therapeutic and diagnostic products." About Proteomics Proteins regulate the activities of cells, tissues and organs. Interactions among proteins can trigger chemical reactions within cells that play a key role in diseases and ailments such as cancer, AIDS and depression. The emerging field of proteomics -- the study of protein location, interaction, structure and function -- aims to identify and characterize the proteins present in normal and diseased biological samples. Abnormalities in protein production or function have been connected to many diseases and health conditions, so the ability to modulate proteins represents an attractive target for drug design. About MDS Proteomics A pioneer in the field of proteomic-enabled drug discovery, MDS Proteomics' goal is to significantly improve the productivity of the pharmaceutical industry in discovering and developing new medicines for the treatment of disease. The company has developed exceptional capabilities in proteomics systems, technology, supercomputing, drug design, screening and biology and is uniquely positioned to build an effective bridge between gene discovery and therapeutic development. This distinctive capability is being used in collaborations with pharmaceutical and biotechnology companies as well as for the development of the company's own product pipeline. In its proteomics facilities in Europe and North America, the company focuses on drug target discovery and validation for both antibody and small molecule therapeutics.
