摘要:
AbstractThe solution structures of several small proteins have recently been determined from high‐resolution nuclear magnetic resonance data. The principal features of the methods available to do this are outlined here, together with the advantages, limitations and future prospects of the techniqu

摘要:
AbstractThe properties of disulphide bonds relevant to their roles in stabilizing protein conformation are reviewed. Natural disulphides can stabilize folded conformations substantially, in some cases to much greater extents than would be expected from just entropic effects on the unfolded state. The linkage relationship between conformational stability and disulphide stability is illustrated. Disulphides will not, however, increase protein stability if the disulphides are not maintained in the unfolded state or if instability is caused by processes, such as chemical modification or proteolysis, that are not linked to unfolding, either local or global. This is part of the reason why some recent attempts to increase protein stability by introducing new disulphides have had only modest success. Other reasons appear to be the severe energetic constraints on disulphide bond geometry and, in some cases, unfavourable effects of introducing Cys residues by mutation.

摘要:
AbstractLoop regions in proteins have traditionally been described as ‘random coil’, although they are known to adopt well‐defined conformations in most globular proteins. In this contribution we summarize the results of detailed analysis of the structures and sequences of these loop regions in proteins of known three‐dimensional structure. We also describe how these results can be used as an aid to protein design, modification and mo

摘要:
AbstractHuman monoclonal antibodies are extremely difficult to obtain by hybridoma technology. As an alternative, ‘human‐like’ antibodies have been produced by recombinant DNA technology. The first such engineered antibodies consisted of chimaeric proteins, in which murine variable regions were linked to human constant regions. More recently ‘human’ antibodies have been ‘reshaped’ by transplanting the binding site of a murine antibody into a human antibody. Further‐more antibodies have been dissected into groups of domains (Fab's, Fc's) and for example, Fab's have been joined to enzymes resulting in antibody‐enzyme chimaeras. In addition to their potential clinical applications, engineered antibodies will prove invaluable in studies of structure/function relationships of variable and

摘要:
AbstractVertebrate haemoglobin (Hb), the oxygen‐carrying protein of the blood, consists of two α‐ and two β‐subunits, each containing one haem, and shows cooperative oxygen binding known as the haem–haem interaction. The amino‐acid sequences of Hbs found in different species have diverged considerably and the homology in the most distantly related ones is only 40%. How can such varied amino‐acid sequences give rise to similar three‐dimensional structures and functional properties? To what extent do amino‐acid replacements affect the structure of haemoglobin? Which mutations are responsible for the functional differences between haemoglobins from different species? Expression of α‐ and β‐globins inEscherichia colihas enabled us to introduce any mutations in the haemoglobin molecule at will. By X‐ray crystallographic and functional studies of the engineered mutants, we are trying
