There was some intense competition among several groups worldwide for solving the 3D structure of tRNA during the sixties and early seventies.
[3] At a symposium held in June 1974, both Rich and Robertus from Klug's group presented their results with little detail.
Afterwards Klug's group argued and complained to Francis Crick that Rich's group published a paper in Science [4] within a month of the symposium influenced by what they had heard which differed in some details from Rich's earlier 3 Å structure.
There had been a breakdown of communication between the MIT and Duke groups in 1973-1974, during which period the models were developed independently.
In 2001, Kim co-founded Plexxikon with Professor Joseph Schlessinger of Yale University.
Plexxikon uses a pioneering structural biology-based platform as a technique for drug discovery and development.
