Crystallographic Evidence for the Tetrameric Subunit Structure of L-Asparaginase from Escherichia coli.

The analysis of a monoclinic crystal modification of L-asparaginase from Eseherichia coli supports the chemical and physico-chemical evidence for a tetrameric subunit structure. The pseudo-symmetries occurring in the crystal structure provide evidence that the molecules lie on positions with approximate point symmetry 222. [ABSTRACT FROM AUTHOR]
