| Abstract |
The serA gene of Escherichia coli strain K-12, which codes for the cooperative allosteric enzyme D-3-phosphoglycerate dehydrogenase, was inserted into an inducible expression vector which produced phosphoglycerate dehydrogenase as 8% of the soluble protein of E. coli. The purified protein was used to grow several different single crystal forms. One of these, with space group P2(1), appears to contain all four subunits of the tetrameric enzyme in the asymmetric unit and diffracts to sufficient resolution to allow determination of the structure of phosphoglycerate dehydrogenase. |
