The antibody repertoire is very large with at least 10(9) different antibody specificities, yet there are currently only 800 variable-region sequences known and < 23 Fab structures deposited with the Brookhaven Protein Data Bank. To engineer the antibody-combining site rationally, we need to define the rules that govern antibody structure. To understand the process of antibody-antigen recognition, we need not only to predict complementary determining regions accurately, but to simulate accurately the interaction of antibody with antigen. We have made progress in the modeling of antibody-combining sites and in the simulation of antibody complex formation. The combination of these approaches will allow us to extend the natural limits of antibody-combining sites in a more rational manner.

D011487 Protein Conformation The characteristic 3-dimensional shape of a protein, including the secondary, supersecondary (motifs), tertiary (domains) and quaternary structure of the peptide chain. PROTEIN STRUCTURE, QUATERNARY describes the conformation assumed by multimeric proteins (aggregates of more than one polypeptide chain). Conformation, Protein,Conformations, Protein,Protein Conformations

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015202 Protein Engineering Procedures by which protein structure and function are changed or created in vitro by altering existing or synthesizing new structural genes that direct the synthesis of proteins with sought-after properties. Such procedures may include the design of MOLECULAR MODELS of proteins using COMPUTER GRAPHICS or other molecular modeling techniques; site-specific mutagenesis (MUTAGENESIS, SITE-SPECIFIC) of existing genes; and DIRECTED MOLECULAR EVOLUTION techniques to create new genes.
