Structural biology: Designer labels

Stanley J. Opella1

Top

An innovative approach to the isotopic labelling of proteins places the determination of the structures of larger proteins — particularly those in solution — within reach, while improving the accuracy of the method.

With completion of the sequencing of the human and many other genomes, molecular biology is able to return to its roots to focus on, as Francis Crick1 put it, "the description of [proteins, viruses, bacteria and chromosomes] in terms of their structure, i.e.
