Abstract
The model for ferredoxin from Peptococcus aerogenes, derived from a 2.8-A resolution map, has been refined with a 2-A resolution data set. The conventional index, R, decreased from 0.449 for the initial model to 0.188 for the unconstrained one and 0.206 for the constrained one. The standard deviations of the iron and sulfur atoms are 0.04 to 0.05 A and for the oxygen, nitrogen, and carbon atoms they range from 0.14 to 0.26 A. One hundred forty-six water oxygen atoms were included in the solvent part of the model and were checked by a highly selective criterion, suggesting that most of them represented water molecules.
