ASPARAGINASE FROM ERWINIA CHRYSANTHEMI, HEXAGONAL FORM WITH WEAK SULFATE
OverviewOverview
Quasi-enantiomorphic crystals of the Y25F mutant of Escherichia coli, L-asparaginase and of the native Erwinia chrysanthemi L-asparaginase were, obtained in the hexagonal space groups P6(5)22 and P6(1)22, respectively., The structures of these highly homologous enzymes were solved by molecular, replacement and were refined with data extending to 2.2-2.5 A. These, structures were compared with each other, as well as with other, L-asparaginase structures previously observed with different crystal, packing. It is concluded that the observed phenomenon, which is rare, was, most likely to have arisen by chance.
