Along with colleague Harold W. Wyckoff, who had worked on early research toward the myoglobin structure,[20] the effort to solve the RNase S 3-dimensional structure was spearheaded by Richards. Done in 1966 and published in 1967, the analyses of RNase S [21] and RNase A[22] jointly made ribonuclease the third distinct protein structure to be determined by X-ray diffraction of crystals, after
myoglobin/hemoglobin and hen-egg lysozyme,[23] and the first to be done in the United States. Later, the Yale group collected more diffraction data, and in 1970 published the RNase S structure in full detail at 2.0 Å resolution (Wyckoff et al., 1970). Coordinates for ribonuclease S were deposited into the international Protein Data Bank in 1973 as PDB: 1RNS, among the first small set of macromolecular structures.[24]
