Proteins are the servants of life. They occur in all com- nent parts of living organisms and are staggering in their fu- tional variety, despite their chemical similarity. Even the simplest single-cell organism contains a thousand different p- teins, fulfilling a wide range of life-supporting roles. Additions to the total number of known proteins are being made on an increasing scale through the discovery of mutant strains or their production by genetic manipulation. The total international protein literature could fill a medi- sized building and is growing at an ever-increasing rate. The reader might be forgiven for asking whether yet another book on proteins, their properties, and functions can serve a useful purpose. An explanation of the origin of this book may serve as justification. The authors form the tutorial team for an int- sive postexperience course on protein characterization or- nized by the Center for Professional Advancement, East Brunswick, New Jersey, an educational foundation. The course was first mounted in Amsterdam in 1982 and has since been repeated several times, in both Amsterdam and the US, with participants from North America and most European countries. In a predecessor to this book, emphasis was placed on the role of protein isolation in the food industry, because at the time this reflected the interests of most of the participants at the course. Today, isolated proteins for food use are extracted from yeasts, fungal sources, legumes, oilseeds, cereals, and leaves.
Protein hydrolysates, otherwise commonly known as peptones or peptides, are used in a wide variety of products in fermentation and biotechnology industries. The term “peptone” was first introduced in 1880 by Nagelli for growing bacterial cultures. However, later it was discovered that peptones derived from the partial digestion of proteins would furnish organic nitrogen in readily available form. Ever since, p- tones, which are commonly known as protein hydrolysates, have been used not only for growth of microbial cultures, but also as nitrogen source in commercial fermen- tions using animal cells and recombinant microorganisms for the production of value added products such as therapeutic proteins, hormones, vaccines, etc. Today, the characterization, screening and manufacturing of protein hyd- lysates has become more sophisticated, with the introduction of reliable analytical instrumentation, high throughput screening techniques coupled with statistical design approaches, novel enzymes and efficient downstream processing equipment. This has enabled the introduction of custom-built products for specialized appli- tions in diverse fields of fermentation and biotechnology, such as the following. 1. Protein hydrolysates are used as much more than a simple nitrogen source. For example, the productivities of several therapeutic drugs made by animal cells and recombinant microorganisms have been markedly increased by use of p- tein hydrolysates. This is extremely important when capacities are limited. 2. Protein hydrolysates are employed in the manufacturing of vaccines by ferm- tation processes and also used as vaccine stabilizers.

The present title Protein Biotechnology tries to capture the field of biotechnology in its whole some entirety in a manner that is concise and easily understood by the students. Enzymatic proteins play a vital role in degradation and fermentation providing a well known example but more recent developments of an over increasing range of raw materials have led to a wider and greater impact on the biotechnology industry. Because it is undergoing such rapid growth, there will almost certainly be many examples of protein biotechnology in actual application when this book appears which had not reached that stage when it was written. For this reason we have allowed ourselves to include some examples which look as if they are likely to find application in the near future, despite our endeavour to illustrate the technology be examples that are actually in use, rather than possible processes that might one day find application but all too often really illustrate unfulfilled promise.

The fractionation of human blood plasma can be considered to be a mature industry, with the basic technology, alcohol fractionation, dating back at least to the 1940s. Many of the products described in the current work have been approved biologics since the 1950s. The information gathered from the development of plasma proteins has proved vital to the development of recombinant therapeutic proteins. Discussing the role of plasma proteins in current biotechnology, Biotechnology of Plasma Proteins describes the protein composition of human plasma, the fractionation of plasma to obtain therapeutic proteins, and the analysis of these products. It delineates the path from plasma products to recombinant products, and highlights products from albumin, intravenous immunoglobins, and coagulation. It offers a comprehensive review of current techniques for the analysis of proteins including electrophoresis, chromatography, spectrophotometry, mass spectrometry, and updates not published since 1975. Key Topics Protein Composition of Plasma Proteomic methods for plasma protein analysis Plasma protein biomarkers Validation of biomarkers Assays for plasma biomarkers Methods for the Analysis of Protein Products Assay development and validation Electrophoresis Chromatography Immunoassay Mass spectrometry Raman spectroscopy Plasma Fractionation: Historical and Modern Methods Development of Cohn alcohol fractionation Industrial methods Development of chromatographic methods Plasma Protein Products of Therapeutic Value Albumin Intravenous immunoglobulin Coagulation products Growth factors Wound management

Protein engineering has proved to be one of the more fruitful technological approaches in biotechnology, being both very powerful and able to generate valuable intellectual property. This book aims to present examples in which the application of protein engineering has successfully solved problems arising in industrial biotechnology. There is a section on its use to enhance purification of recombinant proteins. The use of protein engineering to modify the activity or the stability of industrial enzymes from lipases to proteases, from carboxypeptidases to glucanases and glucosidases, and from pectin modifying enzymes to enzymes able to degrade recalcitrant compounds is extensively covered. It is shown how areas as diverse as agrofood technology, fine chemistry, detergents, bioremediation and biosensors receive significant contributions from protein and solvent engineering. The application of protein engineering to health care is also covered, from the development of new vaccines to new potential therapeutic proteins. A specific notation is given to protein engineering in the development of target molecules for drug discovery. International in scope, the many contributions are drawn from academia and industry. The text should be of interest to students and researchers in industrial biotechnology as well as to everybody interested in basic research in protein structure, molecular genetics, bio-organic chemistry, biochemistry, agrobiotechnology, pharmaceutical sciences and medicine.
